Section 5 Miscellaneous Topics
Section 5 Miscellaneous Topics
intro(5) intro(5) NAME intro - introduction to miscellany DESCRIPTION This section describes miscellaneous facilities, such as: macro packages, character set tables, the file system hierarchy, and operating system tunable parameters. SEE ALSO introduction(9). A A Other Documentation • Tunable Kernel Parameters • HP-UX on the Internet at http://docs.hp.com.
acctsuspend(5) acctsuspend(5) (Tunable Kernel Parameters) NAME acctsuspend, acctresume - suspend and resume accounting when available disk space reaches threshold VALUES Failsafe Default.
acctsuspend(5) acctsuspend(5) (Tunable Kernel Parameters) AUTHOR acctsuspend and acctresume were developed by HP. SEE ALSO accton(1M).
acl(5) acl(5) NAME acl - introduction to HFS access control lists DESCRIPTION Access control lists are a key enforcement mechanism of discretionary access control (see Definitions below), for specifying access to files by users and groups more selectively than traditional HP-UX mechanisms allow.
acl(5) acl(5) Access Control List Entries An access control list (ACL) consists of sets of (user.group, mode) entries associated with a file that specify permissions. Each entry specifies for one user-ID/group-ID combination a set of access permissions, including read, write, and execute/search.
acl(5) acl(5) ACL Uniqueness Entries are unique in each ACL. There can only be one (u.g, mode) entry for any pair of u and g values; one (u.%, mode) entry for a given value of u; one (%.g, mode) entry for a given value of g; and one (%.%, mode) entry for each file. For example, an ACL can have a (23.14, mode) entry and a (23.%, mode) entry, but not two (23.14, mode) entries or two (23.%, mode) entries. Access Check Algorithm ACL entries can be categorized by four levels of specificity.
acl(5) acl(5) The exact syntax is: acl entry id op mode char ::= ::= ::= ::= ::= ::= [entry[,entry]...] id . id op mode [op mode]... name | number | % | @ = | + | 0..7 | [char[char]...] r | w | x Short Form of ACLs (input and output) (user . group, mode) ... A Short form differs from operator form in several ways: • Entries are surrounded by parentheses rather than being separated by commas. • Each entry specifies the mode, including all mode bits.
acl(5) acl(5) ACL Patterns Some library calls and commands recognize and use ACL patterns instead of exact ACLs to allow operations on all entries that match the patterns. ACL syntax is extended in the following ways: wildcard user and group IDs A user or group name of * (wildcard) matches the user or group ID in any entry, including % (no specific user or group).
acl(5) acl(5) The st_mode field contains a user-dependent summary, so that programs ignorant of ACLs that use stat (2) and chmod(2) are more likely to produce expected results, and so that stat (2) provides reasonable information about remote files over NFS. The st_basemode and st_acl fields are useful only for local files. chmod For conformance with IEEE Standard POSIX 1003.1-1988, chmod(2) deletes any optional entries in a file’s ACL.
acl(5) acl(5) chacl ’(bill.%,-w-)’ myfile The following sets the entry for user 12 in group 4 to allow read and write. chacl ’(12.4,wr)’ myfile The following sets the base ACL entry for the file’s owner to allow both read and execute, and sets write and execute capabilities for ‘‘other’’ users (the ‘‘%.%’’ entry). chacl ’(@.%, 5) (%.%, xwx)’ myfile A aA Long Form Here is the same ACL as in an earlier example, printed in long form. r-x --r-r-x r-- jpc.adm ajs.trux jpc.% %.bin %.
acl(5) acl(5) NGROUPS_RGID NGROUPS_SGID NGROUPS_SUPP NGROUPS_EGID_SUPP NGROUPS_RGID_SUPP NGROUPS_SGID_SUPP process’s real gid process’s saved gid process’s supplementary groups only process’s eff gid plus supp groups process’s real gid plus supp groups process’s saved gid plus supp groups Header The header file defines several constants for use with ACL support library calls.
acl(5) acl(5) DEPENDENCIES NFS NFS does not support ACLs on remote files. Individual manual entries specify the behavior of various system calls, library calls, and commands under these circumstances. Be careful when transferring a file with optional entries over a network or when manipulating a remote file because optional entries may be silently deleted. AUTHOR The access control list design described here was developed by HP. A aA FILES
aclv(5) aclv(5) NAME aclv - introduction to JFS access control lists (ACLs) DESCRIPTION Access control lists (ACLs) are a key enforcement mechanism of discretionary access control (see Definitions below), for specifying access to files by users and groups more selectively than traditional HPUX mechanisms allow.
aclv(5) aclv(5) Access Control List Entries An access control list (ACL) consists of a set of one-line entries associated with a file that specify permissions. Each entry specifies for one user-ID or group-ID a set of access permissions, including read, write, and execute/search.
aclv(5) aclv(5) ACL entries (except for the first user [owner] entry and the other entry). Any permission can be denied to a particular user or group. The class entry acts as a upper bound for file permissions. When an ACL contains more than one user and/or group entry, the collection of additional user and group entries are referred to as the groupclass entries, since the effective permission granted by any of these additional entries is limited by the class entry.
aclv(5) aclv(5) default:user:beta:r-default:user:gamma:r-default:group:dos:--default:group:tres:--Access Check Algorithm To determine the permission granted to an accessing process’s effective user ID (EGID) and effective group ID (EGID), respectively, the following checks are made, in the following order: A aA If the EUID of the process is the same as the owner of the file, grant the permissions specified in the user:: entry.
aclv(5) aclv(5) Header The header defines constants for use with getaccess (2).
aio(5) aio(5) NAME aio - POSIX asynchronous I/O facility SYNOPSIS #include A aA DESCRIPTION The POSIX Asynchronous I/O facility implements Section 6.7 of IEEE Standard 1003.1b-1993, Standard for Information Technology, Portable Operating System Interface (POSIX), Part 1: System Application Program Interface (API), Amendment 1: Realtime Extensions (C Language).
aio(5) aio(5) Manifest Constants Certain values as defined by the POSIX standard are declared in aio.h. The following values are returned by the aio_cancel() function: AIO_CANCELED All specified asynchronous I/O operations were successfully canceled. AIO_NOTCANCELED At least one specified asynchronous I/O operations was not successfully canceled. AIO_ALLDONE All specified asynchronous I/O operations were completed before the request was processed.
aio(5) aio(5) The specified notification, if any, is then performed when the operation completes. The aio_suspend() function allows the application to wait for completion of one or more asynchronous I/O operations. A timeout may be set so that the process can again execute and take appropriate recovery actions if the expected operations do not complete as expected. If the aio_suspend() references multiple operations, return is made when any one of the operations completes.
aio(5) aio(5) The maximum priority change that can be specified in aio_reqprio is limited. The maximum priority change value is tunable. The current maximum value can be obtained using the sysconf() call with the argument _SC_AIO_PRIO_DELTA_MAX. The default value is 20. The maximum number of asynchronous I/O operations that can be specified in a single lio_listio() call is limited. This limit is tunable.
aio_listio_max(5) aio_listio_max(5) (Tunable Kernel Parameters) NAME aio_listio_max - the maximum number of POSIX asynchronous I/O operations that can be specified in a listio() call VALUES Failsafe 256 Default A aA 256 Allowed values The minimum value allowed is 2. The maximum value allowed is 0x100000. The value is further constrained in that it must be less than or equal to aio_max_ops. Specify a positive integer value.
aio_max_ops(5) aio_max_ops(5) (Tunable Kernel Parameters) NAME aio_max_ops - maximum number of POSIX async I/O operations that can be queued at any time VALUES Failsafe 2048 Default 2048 Allowed values The minimum value allowed is 2. The maximum value allowed is 0x100000. The value is further constrained in that it must be greater than or equal to aio_listio_max. Specify a positive integer value.
aio_monitor_run_sec(5) aio_monitor_run_sec(5) (Tunable Kernel Parameters) NAME aio_monitor_run_sec - frequency of AIO thread pool monitor execution (in seconds) VALUES Failsafe 2 Default 30 A aA Allowed values 1-60 Recommended values 1-60 DESCRIPTION The implementation of POSIX AIO on HP-UX uses kernel threads to perform I/Os to filesystems that do not directly support true asynchronous I/O. (This distinction is transparent to the user.
aio_monitor_run_sec(5) aio_monitor_run_sec(5) (Tunable Kernel Parameters) for bursty or periodic I/O loads, this should maximize performance. What Other Tunables Should Be Changed at the Same Time as This One? aio_proc_threads interacts with this tunable by setting a strict limit on the number of threads that can be used for POSIX AIO.
aio_physmem_pct(5) aio_physmem_pct(5) (Tunable Kernel Parameters) NAME aio_physmem_pct - percentage of physical memory lockable for request call-back POSIX asynchronous I/O operations VALUES Failsafe 10 Default A aA 10 Allowed values The minimum value allowed is 5. The maximum value allowed is 50. Specify a positive integer value.
aio_physmem_pct(5) aio_physmem_pct(5) (Tunable Kernel Parameters) SEE ALSO kctune(1M), sam(1M), gettune(2), settune(2), aio(5), aio_return(2), dmesg(1M), mlock(2), plock(2), getrlimit(2), setrlimit(2), unlockable_mem(5).
aio_prio_delta_max(5) aio_prio_delta_max(5) (Tunable Kernel Parameters) NAME aio_prio_delta_max - greatest delta (slowdown factor) allowed in POSIX async IO request priorities VALUES Failsafe 20 Default 20 A aA Allowed values The minimum value allowed is 0. The maximum value allowed is 20. Specify a positive integer value. DESCRIPTION This parameter places a limit on how much the priority of a POSIX asynchronous I/O operation can be reduced to slow it down.
aio_proc_threads(5) aio_proc_threads(5) (Tunable Kernel Parameters) NAME aio_proc_threads - maximum number of process threads allowed in AIO pool VALUES Failsafe 256 Default 1024 A Allowed values 4-2048 Recommended values 32-2048 DESCRIPTION The implementation of POSIX AIO on HP-UX uses kernel threads to perform I/Os to filesystems that do not directly support true asynchronous I/O. (This distinction is transparent to the user.
aio_proc_threads(5) aio_proc_threads(5) (Tunable Kernel Parameters) What Other Tunables Should Be Changed at the Same Time as This One? aio_proc_thread_pct interacts with this tunable by setting a limit on the number of AIO threads based on a percentage of the maximum number of allowable process threads. This allows the AIO thread pools to respond dynamically to changes in max_thread_proc.
aio_proc_thread_pct(5) aio_proc_thread_pct(5) (Tunable Kernel Parameters) NAME aio_proc_thread_pct - percentage of all process threads allowed in AIO pool VALUES Failsafe 50 Default 70 A Allowed values 10-100 Recommended values 10-90 DESCRIPTION The implementation of POSIX AIO on HP-UX uses kernel threads to perform I/Os to filesystems that do not directly support true asynchronous I/O. (This distinction is transparent to the user.
aio_proc_thread_pct(5) aio_proc_thread_pct(5) (Tunable Kernel Parameters) What Other Tunables Should Be Changed at the Same Time as This One? aio_proc_threads interacts with this tunable by setting a strict limit on the number of threads that can be used for POSIX AIO. This allows a hard limit to be imposed, regardless of what value max_thread_proc happens to take. aio_req_per_thread defines the desired relationship between the number of POSIX AIO kernel threads and the number of I/Os to be serviced.
aio_req_per_thread(5) aio_req_per_thread(5) (Tunable Kernel Parameters) NAME aio_req_per_thread - desirable ratio between number of pending AIO requests and servicing threads VALUES Failsafe 4 Default 1 A Allowed values 1-100 Recommended values 1-100 DESCRIPTION The implementation of POSIX AIO on HP-UX uses kernel threads to perform I/Os to filesystems that do not directly support true asynchronous I/O. (This distinction is transparent to the user.
aio_req_per_thread(5) aio_req_per_thread(5) (Tunable Kernel Parameters) What Other Tunables Should Be Changed at the Same Time as This One? aio_proc_threads interacts with this tunable by setting a strict limit on the number of threads that can be used for POSIX AIO. aio_proc_thread_pct interacts with this tunable by setting a limit on the number of threads that can be used for POSIX_AIO, but does so based on a percentage of the maximum number of allowable process threads.
aliases(5) aliases(5) NAME aliases - aliases file for sendmail SYNOPSIS /etc/mail/aliases DESCRIPTION The newaliases command (which is the same as sendmail -bi; see sendmail (1M)) builds the sendmail alias database from a text file. The default text file is /etc/mail/aliases. Local addresses (local user names) are looked up in the alias database and expanded as necessary, unless the user name is preceded by a backslash (\).
aliases(5) aliases(5) /etc/mail/aliases is only the raw data file. The actual aliasing information is placed into a binary format in the file /etc/mail/aliases.db using newaliases (see newaliases (1M)). A newaliases command should be executed each time the aliases file is changed in order for the change to take effect. Note that the NIS alias maps are generated by ypmake using makemap, which leaves aliases.pag and aliases.dir in the /etc/mail directory.
allocate_fs_swapmap(5) allocate_fs_swapmap(5) (Tunable Kernel Parameters) NAME allocate_fs_swapmap - determines when swapmap structures are allocated for filesystem swap VALUES Failsafe 0 (off) Default 0 (off) A Allowed values 1 (on) or 0 (off) DESCRIPTION The allocate_fs_swapmap tunable is used to determine whether to allocate all needed filesystem swap structures during the initialization of the filesystem swap device or wait until they are needed.
alwaysdump(5) alwaysdump(5) (Tunable Kernel Parameters) NAME alwaysdump - defines which classes of kernel memory pages are dumped when a kernel panic occurs VALUES Failsafe 0 Default 0 (Allow the kernel to choose which classes to dump.) A aA Allowed values Integer values from 0 to 255.
alwaysdump(5) alwaysdump(5) (Tunable Kernel Parameters) Note that certain types of system crash, require a full crash dump. Also, the system operator may request a full crash dump at the time the dump is taken. In either of these cases, a full dump will be performed regardless of the classes selected using alwaysdump. Who Is Expected to Change This Tunable? Only HP Field engineers should change the value of this tunable. Restrictions on Changing Changes to this tunable take effect at next reboot.
Aries(5) Aries(5) (Itanium(R)-Based Processor Family Only) NAME Aries - emulate PA-RISC applications on Itanium-based processor family DESCRIPTION Aries is a binary emulator that transparently emulates 32-bit and 64-bit HP-UX PA-RISC applications on HP-UX Itanium-based machines. Aries is transparent in that: A aA • The HP-UX PA-RISC application is not re-compiled. • The user does not explicitly invoke Aries.
Aries(5) Aries(5) (Itanium(R)-Based Processor Family Only) 3. No support for conditional reporting of system call entry and exit events. 4. No support for old gdb versions (of HP-UX 10.20 and earlier). However, debugging HP-UX 10.20 applications using a HP-UX 11.0 PA gdb is supported. 5. PA gdb behaves differently for child programs created using fork() and vfork().
Aries(5) Aries(5) (Itanium(R)-Based Processor Family Only) found by Aries, or, if .ariesrc file is found but -fast_trans is not found in that file, then Aries uses the old translator as the default. 3. Warning Due to the beta-nature of this translator, the users need to be aware that an element of risk is involved in deploying the beta translator for mission-critical applications.
Aries(5) Aries(5) (Itanium(R)-Based Processor Family Only) program sees a complete PA environment on Itanium-based system. If the application requires that it be able to determine that it is running on an Itanium-based machine then one method is for the application to use the system (3S) call and utilize the Itanium-based native command, getconf (1), to get the required fields. See system (3S), getconf (1) and sysconf (2) for more details. SEE ALSO ulimit(2), setrlimit(2), signal(2), gdb(1), core(4).
ascii(5) ascii(5) NAME ascii - map of ASCII character set SYNOPSIS cat /usr/share/lib/pub/ascii DESCRIPTION The /usr/share/lib/pub/ascii file provides a map of the ASCII character set, giving both octal and hexadecimal equivalents of each character.

core_addshmem_read(5) core_addshmem_read(5) (Tunable Kernel Parameters) NAME core_addshmem_read - determines the inclusion of readable shared memory in a process core dump VALUES Failsafe 0 (off) Default 0 (off) Allowed values 1 (on) or 0 (off) A cA DESCRIPTION The core_addshmem_read tunable was added in response to a problem where a customer was limited in debugging a user-level process crash because shared memory segments were not written as part of the core file.
core_addshmem_write(5) core_addshmem_write(5) (Tunable Kernel Parameters) NAME core_addshmem_write - determines the inclusion of read/write shared memory in process core dump VALUES Failsafe 0 (off) Default 0 (off) Allowed values 1 (on) or 0 (off) DESCRIPTION The core_addshmem_write tunable was added in response to a problem where a customer was limited in debugging a user-level process crash because shared memory segments were not written as part of the core file.
create_fastlinks(5) create_fastlinks(5) (Tunable Kernel Parameters) NAME create_fastlinks - configure the system to use fast symbolic links VALUES Minimum 0 Maximum 1 Default 0 A cA Specify integer value. DESCRIPTION When create_fastlinks is nonzero, it causes the system to create HFS symbolic links in a manner that reduces the number of disk-block accesses by one for each symbolic link in a path name lookup.

dld.so(5) dld.so(5) NAME dld.so - dynamic loader MULTITHREAD USAGE The dynamic loader is thread-safe. A dA DESCRIPTION The /usr/lib/hpux64/dld.so shared library is the 64-bit dynamic loader. The /usr/lib/hpux32/dld.so shared library is the 32-bit dynamic loader. In programs that use shared libraries, dld.so is invoked automatically at startup time. /usr/ccs/lib/hpux64/crt0.o is the 64-bit run-time startup file. /usr/ccs/lib/hpux32/crt0.o is the 32-bit run-time startup file. The /usr/lib/hpux32/uld.
dld.so(5) dld.so(5) path or embedded path set by the ld +b command) and the default directory /usr/lib/hpux64 for 64-bit libraries or the default directory /usr/lib/hpux32 for 32-bit libraries.
dld.so(5) dld.so(5) If the -B immediate option to ld is used, the loader binds all necessary references at startup time. This increases the startup cost of a program, but ensures that no more binding operations are required later. Thus, better real-time response may result, and the risk of a later abort due to unresolved externals is eliminated. The fastbind tool can be used to improve the start-up time of programs that use shared libraries (incomplete executables).
dld.so(5) dld.so(5) linker. Use the +gst options, +gst, +gstsize, and +nodynhash, to control the behavior of the global symbol table hash mechanism. See the ld(1) and chatr (1) commands for information on these options. With these options, you can tune the size to reach a balance of performance and memory use. To maximize for performance, tune the table size for an average chain length of one.
dld.so(5) dld.so(5) The LD_PRELOAD Environment Variable NOTE: The LD_PRELOAD feature is disabled for seteuid/setegid programs, such as passwd. See ld(1) for more details. This feature is not available to fully-bound static executables. The LD_PRELOAD environment variable allows you to load additional shared libraries at program startup. LD_PRELOAD provides a colon-separated or space-separated list of shared libraries that the dynamic loader can interpret. The dynamic loader, dld.
dld.so(5) dld.so(5) while attaching a shared library include library not present, library not executable, library corrupt, high water mark too low, or insufficient room in the address space for the library. Possible errors that can occur while binding symbols include symbol not found (unresolved external), or library corrupt. When using the explicit load facilities of the dynamic loader, these types of errors are not considered fatal.

gssapi(5) gssapi(5) NAME gssapi - Generic Security Service Application Programming Interface DESCRIPTION This introduction includes general information about the Generic Security Service Application Programming Interface (GSSAPI) defined in "Internet RFC 2743, Generic Security Service Application Programming Interface," and "RFC 2744, Generic Security Service API: C-bindings.
gssapi(5) in the gssapi(5) normal way to the context acceptor. The acceptor passes this token to the gss_accept_sec_context() routine, which generates a delegated credential. The context acceptor can use the credential to initiate additional security contexts. The applications can exchange protected messages and data using this context. The applications can call GSSAPI routines to protect data exchanged in messages.
gssapi(5) gssapi(5) } gss_buffer_desc, *gss_buffer_t; The length field contains the total number of bytes in the data and the value field contains a pointer to the actual data. When using the gss_buffer_t data type, the GSSAPI routine allocates storage for any data it passes to the application. The calling application must allocate the gss_buffer_desc object. It can initialize unused gss_buffer_desc objects with the value GSS_C_EMPTY_BUFFER.
gssapi(5) gssapi(5) The gss_ctx_id_t data type contains an atomic value that identifies one end of a GSSAPI security context. The data type is opaque to the caller. Authentication Tokens GSSAPI uses tokens to maintain the synchronization between the applications sharing a security context. The token is a cryptographically protected bit string generated by the security mechanism at one end of the GSSAPI security context for use by the peer application at the other end of the security context.
gssapi(5) gssapi(5) GSS_S_UNAUTHORIZED 15 The operation is forbidded by local security policy. The following table lists the calling error values and their meanings: Name GSS_S_CALL_INACCESSIBLE_READ Field Value 1 GSS_S_CALL_INACCESSIBLE_WRITE 2 GSS_S_BAD_STRUCTURE 3 Meaning Could not read a required input parameter. Could not write a required output parameter. A parameter was incorrectly structured. The following table lists the supplementary bits and their meanings.
gssapi(5) gssapi(5) Names are represented in two forms: A printable form, for presentation to an application. An internal, canonical form that is used by the APIs and is opaque to applications. The gss_import_name() and gss_display_name() routines convert names between their printable form and their gss_name_tdata type. The gss_compare_name() routine compares internal form names.
gssapi(5) gssapi(5) Some security mechanisms check that the initiator_address field of the channel bindings presented to the gss_init_sec_context() routine contains the correct network address of the host system. Therefore portable applications should use either the correct address type and value or the GSS_C_AF_NULLADDR for the initiator_addrtype address field.

Who Is Expected to Change This Tunable? HP Field engineers, but not customers directly.
hier(5) hier(5) NAME hier - file system hierarchy DESCRIPTION The HP-UX file system is a hierarchical tree organized for administrative convenience. Within the filesystem tree structure, distinct areas are provided for files that are private to one machine, files that can be shared by machines, and home directories. There are two types of files that are shared: those that can be shared by multiple machines of a common architecture, and those that can be shared by all machines.
hier(5) hier(5) /sbin/rc3.d Link files to scripts in /sbin/init.d for entering or leaving run level 3. /stand Standalone binaries and kernel configuration files. /tmp System-generated temporary files; generally cleared during the boot operation. /usr Mount point for sharable user and system administration commands, libraries and documentation. /usr/bin Primary location for common utilities and user commands. /usr/ccs C compilation system. Tools and libraries used to generate C programs.
hier(5) hier(5) transient, and spool files. A hA /var/adm System administrative files, such as log files and accounting files. Some of the subdirectories are listed below. /var/adm/crash For saving kernel crash dumps. /var/adm/cron Directory for cron (1M) queuing. /var/adm/sw Default location for software distribution depot. /var/adm/syslog Log files generated by syslog. See syslog (3C) and syslogd (1M). /var/mail Incoming mail. /var/news Local-system news articles for news(1).
hostname(5) hostname(5) NAME hostname - host name resolution description DESCRIPTION Hostnames are domains. A domain is a hierarchical, dot-separated list of subdomains. For example, the machine monet, in the Berkeley subdomain of the EDU subdomain of the Internet Domain Name System would be represented as monet.Berkeley.EDU (with no trailing dot). Hostnames are often used with network client and server programs, which must generally translate the name to an address for use.
hosts_access(5) hosts_access(5) NAME hosts_access - format of host access control files DESCRIPTION The access control facility for internet services uses access control files to grant or deny access to its services. These files are defined using a simple access control language based on client (host name/address, user name) and server (process name, hostname/address) patterns. See the EXAMPLES section for a quick introduction.
hosts_access(5) hosts_access(5) • A string that begins with an at (@) character is treated as an NIS (formerly YP) netgroup name. A host name is matched if it is a host member of the specified netgroup. Netgroup matches are not supported for daemon process names or for client user names. • An expression of the form n.n.n.n /m.m.m.m is interpreted as a "net/mask" pair. A host address is matched if "net" is equal to the bit-wise AND of the address and the "mask". For example, the net/mask pattern 131.
hosts_access(5) hosts_access(5) %n(%N) The client (server) host name (or unknown or paranoid). %p The daemon process id. %s Server information: daemon @host, daemon @address, or just a daemon name, depending on how much information is available. %u The client user name (or unknown). %% Expands to a single % character. Characters in % expansions that do not match any alpha-numeric (A-Za-z0-9) or !@%-_=+:,./ characters are replaced by underscores.
hosts_access(5) hosts_access(5) A positive IDENT lookup result (the client matches KNOWN@host) is less reliable. It is possible for an intruder to spoof both the client connection and the IDENT lookup, although doing so is much harder than spoofing just a client connection. It may also be possible that the client’s IDENT server is lying. NOTE: IDENT lookups do not work with UDP services.
hosts_access(5) hosts_access(5) WARNING: Do not set traps on your finger daemon, unless you are prepared for infinite finger loops. Service trapping can be especially useful on network firewall systems. The typical network firewall only provides a limited set of services to the outer world. All other services can be trapped just like the above tftp example. The result is an excellent early-warning system.
hosts_options(5) hosts_options(5) NAME hosts_options - host access control language extensions DESCRIPTION This manual page describes the optional extensions to the language described in the hosts_access (5) manual page. The extensible language uses the following format: daemon_list : client_list : option : option ... The first two fields are described in the hosts_access (5) manual page. Briefly, daemon_list is a list of one or more daemon process names or wildcards.

ioctl(5) ioctl(5) NAME ioctl - generic device control commands SYNOPSIS #include ioctl(fildes, request, arg) int fildes, request; DESCRIPTION The ioctl (2) system call provides for control over open devices. This include file describes requests and arguments used in ioctl (2) which are of a generic nature. For details about how individual requests will affect any particular device, see the corresponding device manual entry in Section (7).

kconfig(5) kconfig(5) NAME kconfig - introduction to kernel configuration commands DESCRIPTION HP-UX contains a set of commands used to view and modify the configuration of the HP-UX kernel.
kconfig(5) kconfig(5) change will not take effect at next boot. A warning will be printed in these situations. Changes that replace the entire currently running configuration, such as kconfig -i (import), kconfig -l (load), or kconfig -n (nextboot), cause any changes being held for next boot to be discarded. Changes that are made to the currently running system are retained when the system is rebooted. They remain in effect until changed, or until a saved kernel configuration is loaded.
kconfig(5) kconfig(5) Some configuration changes can be made without using the kernel configuration commands. No log file entries are made for such changes. The format of the log file may be changed without notice. Programs must use the kclog command to retrieve entries from the file rather than attempting to parse the file format. PARSING OUTPUT Most of the kernel configuration commands produce tabular output describing the details of a configuration.
kerberos(5) kerberos(5) NAME kerberos - introduction to the Kerberos system DESCRIPTION The Kerberos system authenticates individual users in a network environment. After authenticating yourself to Kerberos, you can use network utilities such as rlogin, rcp, and rsh without having to present passwords to the remote hosts and without having to edit and use .rhosts files. Note that these utilities will work without passwords only if the remote machines you deal with support the Kerberos system.
krs(5) krs(5) NAME krs - kernel registry services DESCRIPTION KRS is a kernel specific mechanism that facilitates the maintenance of structured data. Subsystems within the kernel can use KRS to maintain static or dynamic data. This data can be either volatile, or persistent across system reboot. AUTHOR krs was developed by Hewlett-Packard Company. SEE ALSO krsd(1M), krs_flush(1M).

nswapdev(5) nswapdev(5) (Tunable Kernel Parameters) NAME nswapdev - maximum number of devices that can be enabled for swap VALUES Default 10 devices Allowed values Minimum: 1 device Maximum: 25 devices DESCRIPTION Swap devices are managed in a table for easier indexing in the kernel. nswapdev sets the kernel variable responsible for the upper limit on this table, and thus the upper limit to devices which can be used for swap. Who is Expected to Change This Tunable? Anyone.
nswapfs(5) nswapfs(5) (Tunable Kernel Parameters) NAME nswapfs - maximum number of file systems that can be enabled for swap VALUES Default 10 file systems Allowed values Minimum: 0 file systems Maximum: 25 files systems DESCRIPTION File system swap devices are managed in a table for easier indexing in the kernel. nswapfs sets the kernel variable responsible for the upper limit on this table, and thus the upper limit to file systems which can be used for swap.
nsysmap(5) nsysmap(5) (Tunable Kernel Parameters) NAME nsysmap, nsysmap64 - number of entries in a kernel dynamic memory allocation map VALUES Default 8400 Allowed Values Any positive value. In practice, very small values will likely cause a panic during boot (or soon after) and very large values are probably unnecessary. Changing the tunable from the default is only necessary under certain conditions.
nsysmap(5) nsysmap(5) (Tunable Kernel Parameters) What Other Tunables Should Be Changed at the Same Time? None. WARNINGS All HP-UX kernel tunable parameters are release specific. This parameter may be removed or have its meaning changed in future releases of HP-UX. AUTHOR nsysmap and nsysmap64 were developed by HP.
orientation(5) orientation(5) NAME orientation - the orientation of a stream DESCRIPTION The orientation of a stream is a property of a FILE object that is handled as a input/output stream. It is useful when the input/output model assumes that characters are handled as wide-characters within an application and stored as multi-byte characters in files, and that all the wide-character input/output functions begin executing with the stream positioned at the boundary between two multi-byte characters.
pam_unix(5) pam_unix(5) NAME pam_unix - authentication, account, session, and password management PAM modules for UNIX SYNOPSIS /usr/lib/security/libpam_unix.1 DESCRIPTION The UNIX service module for PAM, /usr/lib/security/libpam_unix.1, provides functionality for all four PAM modules: authentication, account management, session management and password management. The libpam_unix.1 module is a shared object that can be dynamically loaded to provide the necessary functionality upon demand.
pam_unix(5) pam_unix(5) Unix Account Management Module The UNIX account management component provides a function to perform account management (pam_sm_acct_mgmt()). The function retrieves the user’s password entry from the UNIX password database and verifies that the user’s account and password have not expired. For trusted systems, this module also validates the allowed access time and access terminal based upon the security configuration.
pam_unix(5) pam_unix(5) APPLICATION USAGE On trusted systems, the pam_sm_*() interfaces implemented in the UNIX service module, libpam_unix, are not thread-safe. Also they are not thread-safe if the "database" for passwd or publickey specified in the name-service switch configuration file, /etc/nsswitch.conf, is nisplus. Otherwise, they are thread-safe. A cancellation point may occur while a thread is executing any of these interfaces. They are not cancel-safe, async-cancel-safe, nor async-signal-safe.
pam_updbe(5) pam_updbe(5) NAME pam_updbe - User policy definition service module SYNOPSIS /usr/lib/security/libpam_updbe.1 DESCRIPTION The user policy definition service module for PAM, /usr/lib/security/libpam_updbe.1, reads options defined in the user configuration file, /etc/pam_user.conf (see pam_user.conf(4)) and uses pam_set_data (see pam_set_data (3)) to store the information in the pam handle for subsequent service modules to use.

pa_maxssiz(5) pa_maxssiz(5) Itanium(R)-based System Only (Tunable Kernel Parameters) When Should the Value of This Tunable Be Lowered? This tunable should only be lowered if the workload for the PA-RISC emulator is known on the system, more space than is needed is currently used for stack emulation, and swap space (either reserved or allocated) is at a premium on the system.
pfdat_hash_locks(5) pfdat_hash_locks(5) (Tunable Kernel Parameters) NAME pfdat_hash_locks - determines the size of the pfdat spinlock pool VALUES Default 128 Allowed values 64 to 262144 DESCRIPTION Global kernel structures containing information on a running process or memory usage are frequently accessed or modified by several threads concurrently.
pfs_exports(5) pfs_exports(5) NAME pfs_exports, pfs_xtab - directories to export to PFS clients SYNOPSIS /etc/pfs_exports /etc/pfs_xtab DESCRIPTION The /etc/pfs_exports file contains entries for directories that can be exported to PFS clients. This file is read automatically by the pfs_exportfs (1M) command. If you change this file, you must run pfs_exportfs (1M) for the changes to affect the daemon’s operation.
pfs_fstab(5) pfs_fstab(5) NAME pfs_fstab, mtab - static file system mounting table, mounted file systems table SYNOPSIS /etc/pfs_fstab /etc/mtab DESCRIPTION The /etc/pfs_fstab file contains entries for CD-ROM file systems and disc images to mount using the pfs_mount (1M) command, which is normally invoked by rc(1M) script at boot time. This file is used by various utilities such as pfs_mount, and pfs_umount.

SIGN_BIT(int32_t) The SIGN_BIT_MASK macro in the following example will return a sign bit mask for a 32-bit integer.
pthread_stubs(5) pthread_stubs(5) NAME pthread_stubs - list of pthread calls for which the stubs are provided in the C library DESCRIPTION The libc shared libraries in libc cumulative patches, PHCO_22923 (11.00) and PHCO_23772 (11.11) onwards, contain stubs for the pthread functions in libpthread and libcma. The stubs allow nonthreaded applications to dynamically load thread-safe libraries successfully, so that the pthread symbols are resolved.

pthread_stubs(5) pthread_stubs(5) Example 1 An application or any library linked, that requires pthread/cma calls to resolve to the pthread stubs in libc must be built without -lpthread or -lcma on the link line. If -lc is specified before -lpthread or -lcma on the link line, pthread/cma calls resolve to pthread stubs in libc. This may lead to problems as given in the examples below: $ cat thread.c #include #include
pthread_stubs(5) pthread_stubs(5) dynamic /usr/lib/libpthread.1 dynamic /usr/lib/libc.2 shared library binding: deferred global hash table disabled ... Example 2 Specifying -lc before -lpthread in threaded applications can cause run-time problems like the following because the pthread calls get resolved to stubs in libc rather than the functions in pthread library. • Calls to pthread functions fail, due to uninitialized internal structures. • Calls to gethostbyname(3N) fail and return null.
pthread_stubs(5) pthread_stubs(5) Due to the problems mentioned above, -lc should never be specified in the build command of an executable or shared library. By default, the compiler drivers (cc, aCC, f90) automatically pass -lc to the linker at the end of the link line of the executables. To see if a shared library was built with -lc, look at the shared library list in the chatr output (see chatr (1)), or list the dependent libraries with ldd (see ldd(1)): $ cc +z -c lib1.c $ ld -b -o lib1.sl lib1.
pthread_stubs(5) pthread_stubs(5) libc.2. The dependency list of the first case is: a.out / \ lib1 lib2 libc | | libc libpthread / Therefore the load graph is constructed as: lib1.sl --> lib2.sl -->libc.2 --> libpthread.1 This is the desired behavior for non-threaded applications, but causes threaded applications (that use either libpthread or libcma) to fail. lib1.sl specifies -lc, lib2.sl specifies -lpthread and no -lpthread on a.out. $ cc -c +z +DA2.0W lib1.c lib2.c lib1.c: lib2.c: $ ld -b -o lib1.
pthread_stubs(5) pthread_stubs(5) $ cc +DA2.0W thread.c -L. -l1 -l2 $ a.out Error $ ldd a.out lib1.sl => ./lib1.sl lib2.sl => ./lib2.sl libc.2 => /usr/lib/pa20_64/libc.2 libpthread.1 => /lib/pa20_64/libpthread.1 libdl.1 => /usr/lib/pa20_64/libdl.1 $ LD_PRELOAD="/lib/pa20_64/libpthread.1" a.out Success a.out correctly lists -lpthread for a threaded application. $ ld -b -o lib1.sl lib1.o $ ld -b -o lib2.sl -lpthread lib2.o $ cc +DA2.0W thread.c -L. -l1 -l2 -lpthread $ a.out Success $ ldd a.out lib1.sl => .
quota(5) quota(5) NAME quota - disk quotas DESCRIPTION Disk quotas can be used by the system administrator to limit the number of files and file blocks owned by a user on a per-file-system basis. Separate limits can be established for both the number of files (inodes) and the number of 1-Kbyte blocks for each user. A soft (preferred) and a hard limit are established.
quota(5) quota(5) The dqblk64 data structure (defined in ), is used by the quotactl() system call (see quotactl (2)) to get or set quota information for 64-bit filesystems. This structure contains fields that are used to store a user’s current file and block count and quota limits for a particular file system. Note that VxFS 3.5 will track usage in the dqb64_curblocks field only up to 2 TB.
quota(5) quota(5) the chown() system call. The sam command (see sam(1M)) does not yet support disk quotas. When adding new users or file systems, any desired quotas must be established outside of sam. HP has added features to the original implementation to ensure correctness of the content of the quotas file when quotas are enabled by mount and disabled by umount (see mount (1M)), thus eliminating the need to run quotacheck (see quotacheck (1M)).
rcsintro(5) rcsintro(5) NAME rcsintro - description of RCS commands DESCRIPTION Revision Control System (RCS) automates the storing, retrieval, logging, identification, and merging of revisions of ASCII text files. RCS is useful for managing files that are revised frequently. Functions of RCS • Storage and retrieval of revisions of text files. RCS saves revisions in a space efficient way. Revisions can be retrieved by ranges of revision numbers, symbolic names, dates, authors, and states.
rcsintro(5) rcsintro(5) Of course, it is too late now to do the check out with locking, because you probably modified f.c already, and a second check out would overwrite your modifications. Instead, invoke: rcs -l f.c This command will lock the latest revision for you, unless somebody else has already locked it. In that case, you will have to negotiate with that person. Locking assures that you, and only you, can check in the next update, and avoids nasty problems if several people work on the same file.
rcsintro(5) rcsintro(5) path2 are (possibly different or empty) paths and workfile is a filename. • Only the RCS file is given. Then the working file is assumed to be in the current directory and its name is derived from the name of the RCS file by removing path1/ and the suffix ",v". • Only the working file is given. Then the name of the RCS file is derived from the name of the working file by removing path2/ and appending the suffix ",v".
regexp(5) regexp(5) NAME regexp - regular expression and pattern matching notation definitions DESCRIPTION A Regular Expression is a mechanism supported by many utilities for locating and manipulating patterns in text. Pattern Matching Notation is used by shells and other utilities for file name expansion. This manual entry defines two forms of regular expressions: Basic Regular Expressions and Extended Regular Expressions; and the one form of Pattern Matching Notation.
regexp(5) regexp(5) . * [ \ (period, asterisk, left bracket, and backslash) lose their special meaning within a bracket expression. The character sequences: [. [= [: (left-bracket followed by a period, equal-sign or colon) are special inside a bracket expression and are used to delimit collating symbols, equivalence class expressions and character class expressions. These symbols must be followed by a valid expression and the matching terminating .], =], or :].
regexp(5) regexp(5) For example, with the above collating order and assuming that E is a noncollating character, then both the expressions [[=A=]-E] and [d-a] are invalid. An ending range point can also be the starting range point in a subsequent range expression. Each such range expression is evaluated separately. For example, the bracket expression [a-m-o] is treated as [a-mm-o].
regexp(5) regexp(5) \(RE \) A subexpression can be defined within an RE by enclosing it between the character pairs \( and \). Such a subexpression matches whatever it would have matched without the \( and \). Subexpressions can be arbitrarily nested. An asterisk immediately following the \( loses its special meaning and is treated as itself. An asterisk immediately following the \) is treated as an invalid character.
regexp(5) regexp(5) have their special meaning are: . [ \ ( ) * + ? $ | The period, left square bracket, backslash, left parenthesis, right parenthesis, asterisk, plus sign, question mark, dollar sign, and vertical bar are special except when used in a bracket expression (see ERE Bracket Expression). ^ The circumflex is special except when used in a bracket expression in a nonleading position. delimiter Any character used to bound (i.e., delimit) an entire ERE is special for that ERE.
regexp(5) regexp(5) [ ] square brackets * + ? asterisk, plus sign, question mark ^ $ anchoring concatenation alternation | For example, the ERE abba|cde is interpreted as "match either abba or cde. It does not mean "match abb followed by a or c followed in turn by de (because concatenation has a higher order of precedence than alternation). Expression Anchoring An ERE can be limited to matching strings that begin or end a line (i.e.
regexp(5) regexp(5) Patterns Matching Multiple Characters The following rules may be used to construct patterns matching multiple characters from patterns matching a single character: * The asterisk (*) is a pattern that matches any string, including the null string. RERE The concatenation of patterns matching a single character is a valid pattern that matches the concatenation of the single characters or collating elements matched by each of the concatenated patterns.
regexp(5) regexp(5) Multiple alternative patterns in a single clause can be specified by separating individual patterns with the vertical bar character (|); strings matching any of the patterns separated this way will cause the corresponding command list to be selected.

While a process is stopped, any additional signals sent to the process are suspended until the process is restarted (except those marked with Note F above, which are processed immediately). However, when the process is restarted, pending signals are processed.
signal(5) signal(5) process, the process is continued, even if the SIGCONT signal is blocked or ignored. If SIGCONT is blocked and not ignored, the process remains pending until it is either unblocked or a stop signal is generated. Note: When any stop signal (SIGSTOP, SIGTSTP, SIGTIN, SIGTTOU) is posted to threads created with process contention scope, using pthread_kill(), pending SIGCONT signals may not be discarded.
signal(5) signal(5) For SIGFPE, code has the following values: 12 Overflow trap; 13 Conditional trap; 14 Assist exception trap; 22 Assist emulation trap. Refer to the Series 800 processor documentation provided with your system for more detailed information about the meaning of these errors. The Instruction Address Offset Queue (program counter) is not advanced when a trap occurs on Series 800 systems.
sis(5) sis(5) NAME sis - secure internet services with Kerberos authentication and authorization DESCRIPTION Secure Internet Services (SIS) provides network authentication when used in conjunction with HP DCE security services, the HP Praesidium/Security Server, or other software products that provide a Kerberos V5 Network Authentication Services environment.
sis(5) sis(5) access non-secure remote systems. The ftp and telnet daemons have a special command line option (-A) which can be used to ensure that non-secure systems are denied access. To prevent non-secure access through the rcp, remsh or rlogin commands, the inetd.conf file on the remote system should be edited to comment out the entries for shell and login.
sis(5) sis(5) will accompany this error message. This error message will also be generated if the user attempts to access a non-secure remote system. In which case, this message will be preceded by the message: "To bypass Kerberos authentication, use the -P option". This error is reported by ftp, rlogin and telnet. ERROR! Kerberos-specific options are invalid with the -P option. The -P command line option indicates that Kerberos authentication should not be performed.

stdsyms(5) stdsyms(5) NAME stdsyms - description of "named defines" and other specifications for name space from HP-UX header files. DESCRIPTION stdsyms is a description of "named defines" and other specifications that must be set by the application to obtain the appropriate name space from the HP-UX header files. HP-UX header files are organized in a manner that allows for only a subset of the symbols available in that header file to be visible to an application that conforms to a specific standard.
stdsyms(5) stdsyms(5) _AES_SOURCE As documented in the "OSF AES/OS" standard, the programmer is required to define the _AES_SOURCE feature test macro to obtain OSF functionality. This feature test macro can be defined, either by using compiler options (-D_AES_SOURCE) or by using #define directives in the source files before any #include directives. Although the AES does not specify any namespace pollution rules, the other standards have instituted such rules.
stdsyms(5) stdsyms(5) requirements. At the time the function prototypes were introduced in ANSI C, the functions exposed by this flag were only defined in SVID3. _CLASSIC_TYPES The _CLASSIC_TYPES macro can be defined by the programmer to obtain pre-7.0 style function return types and structure element types. This macro has been provided only as a transition aid when migrating from the pre-7.0 version of HP-UX to standards-based HP-UX.

swchunk(5) swchunk(5) (Tunable Kernel Parameters) NAME swchunk - swap chunk size in 1 KB blocks VALUES Default 2048 blocks Allowed values Minimum: 1 blocks Maximum: 65536 blocks DESCRIPTION Swap space in the kernel is managed using ’chunks’ of physical device space. These chunks contain one or more (usually more) pages of memory, but provide another layer of indexing (similar to inodes in file systems) to keep the global swap table relatively small, as opposed to a large table indexed by swap page.
swchunk(5) swchunk(5) (Tunable Kernel Parameters) What Other Tunable Values Should Be Changed at the Same Time? A change to swchunk is independent of any other tunables. WARNINGS All HP-UX kernel tunable parameters are release specific. This parameter may be removed or have its meaning changed in future releases of HP-UX. AUTHOR swchunk was developed by HP.

Default (HZ/10) Where HZ is equal to 100. Allowed values Any value in the range of -1 to 2147483647 is allowed.
timeslice(5) timeslice(5) (Tunable Kernel Parameters) What Are the Side Effects of Lowering the Value? The lowering of the timeslice tunable will result in many more context switches which will increase the time spent in SYSTEM space and less time spent in USER space. Also, the applications that are compute intensive will suffer performance degradation. What Other Tunable Values Should Be Changed at the Same Time? None. WARNINGS All HP-UX kernel tunable parameters are release specific.
timezone(5) timezone(5) (Tunable Kernel Parameters) NAME timezone, dst - difference between Universal (Greenwich mean) time and Local time VALUES Default timezone = 420 dst = 1 A default value of 1, indicates that the default value for the timezone tunable (420 minutes west of Greenwich, England ) is to be interpreted as a daylight savings time value. Allowed values -720 to 720.
types(5) types(5) NAME types - primitive system data types SYNOPSIS #include DESCRIPTION Remarks The example given on this page is a typical version. The type names are in general expected to be present, although exceptions (if any) may be described in DEPENDENCIES.

unwind(5) unwind(5) (Itanium(R)-based System Only) NAME unwind - overview of stack unwind library entry points and convenience macros SYNOPSIS #include DESCRIPTION The header defines the Application Programming Interface (API) of the stack unwind library, supplied as libunwind.so for HP-UX on Itanium-based systems. This page discusses the general concepts of stack unwinding and how the stack unwind library is intended to be used.
unwind(5) unwind(5) (Itanium(R)-based System Only) FEATURES The stack unwind library provides an API for unwinding the stack of a program that conforms to the Itanium Processor Family Software Conventions and Runtime Architecture . The stack unwind library can be used by a process to • Print its own stack trace to standard error or to an output stream, usually for diagnostic purposes. See U_STACK_TRACE(3X) and _UNW_STACK_TRACE(3X).
unwind(5) unwind(5) (Itanium(R)-based System Only) _UNW_STEP_INVALID_BR A branch register value which was marked invalid was encountered in _Unwind_Context during the step process. _UNW_STEP_BAD_BSP_ALIGNMENT The _UNW_currentContext value AR.BSP was not aligned. _UNW_STEP_INVALID_RNAT The AR.RNAT value in _Unwind_Context is marked invalid.
unwind(5) unwind(5) (Itanium(R)-based System Only) uint64_t is a signed 64-bit integer. int32_t is a signed 32-bit integer. int64_t is an unsigned 64-bit integer. The value query and initialization functions use several structures for passing values. They are as follows: Structure _UNW_KernelSavedContext has p10_abi_value and p10_context_value. two fields Structure _UNW_FR_Value has two fields of type uint64_t: second_container.
unwind(5) unwind(5) (Itanium(R)-based System Only) States A state machine is used as an aid to define the legal ordering of the tasks of a stack unwind operation and to describe the stack unwind library’s response to calls from the client. The state machine is defined by eight states and transitions between the states which are triggered by calls to the stack unwind library API functions or in some cases by system conditions such as an out of memory condition.
unwind(5) unwind(5) (Itanium(R)-based System Only) From User_Interrupted_Frame, the client may call _UNW_currentContext or _UNW_step, which transfers the _Unwind_Context into states Frame or Bad. The client may call clear, which transfers the _Unwind_Context into state Init . The client may call _UNW_destroyContext, which transfers the _Unwind_Context into state Stop . Kernel_Bottom_Frame The state indicating the bottom of a kernel call stack.
unwind(5) unwind(5) (Itanium(R)-based System Only) • The Current Frame Marker (CFM). See _UNW_setCFM (3X). • Stacked general registers in the snapshot procedure’s frame as defined by the Current Frame Marker. See previous bullet and _UNW_setCFM (3X). Stepping Once initialization of the _Unwind_Context is complete, it now represents the snapshot procedure’s processor state. The client may call _UNW_step(), which modifies _Unwind_Context to represent the predecessor ’s processor state.
unwind(5) unwind(5) (Itanium(R)-based System Only) scratch BR0 (return link) Value valid only after _UNW_step() across a user space interruption such as a signal handler. Do not attempt to figure out the predecessor’s instruction pointer from BR0. Call _UNW_step() to obtain the _Unwind_Context for the predecessor’s frame and use _UNW_getIP. preserved BR1-BR5 Value valid after successful return from _UNW_step and _UNW_currentContext.
unwind(5) unwind(5) (Itanium(R)-based System Only) _UNW_MEMORY_ALLOCATION_ERROR in the event of a low memory condition. Low Memory Conditions In most cases, a failed construction of an _Unwind_Context leaves the client with enough of an _Unwind_Context object to support a call to the function _UNW_getAlertCode(), which would return _UNW_MEMORY_ALLOCATION_ERROR in the event of a failed construction. Had the construction been successful, _UNW_getAlertCode() would have returned _UNW_OK.
values(5) values(5) NAME values - machine-dependent values SYNOPSIS #include DESCRIPTION This file contains a set of manifest constants, conditionally defined for particular processor architectures. The model assumed for integers is binary representation (one’s or two’s complement), where the sign is represented by the value of the high-order bit. BITS(type ) The number of bits in a specified type (e.g., int).
varargs(5) varargs(5) NAME varargs - handle variable argument list SYNOPSIS #include va_alist va_dcl void va_start(pvar) va_list pvar; type va_arg(pvar, type ) va_list pvar; void va_end(pvar) va_list pvar; DESCRIPTION This set of macros enables programmers to write portable procedures that accept variable argument lists.
varargs(5) varargs(5) receives the variable argument list must pass the address pointer resulting from a call to va_start() on to any subsequent calls that need to access this same variable argument list. All routines that receive this address pointer (v_print_log() in this example) need only to use va_arg() to access the original variable argument list just as if they were the original routine to be passed the variable arguments.

The rest of the format string is * a standard printf(3S) format string. */ if ((*fmt == ’%’) && (*(fmt + 1) == ’Y’)) { FILE *other_fp; fmt += 2; other_fp = (FILE *) va_arg(ap, char *); if (other_fp != (FILE *) NULL) { /* * Print general message information to additional stream. */ (void) vfprintf(other_fp, fmt, ap); (void) fflush(other_fp); } } /* * Now print it to the log file.
vps_ceiling(5) vps_ceiling(5) (Tunable Kernel Parameters) NAME vps_ceiling - maximum (in kilobytes) of system-selectable page size VALUES Default 16 KB Allowed values Minimum: 4 KB Maximum: 65536 KB DESCRIPTION The Translation Look-aside Buffer (TLB) is a microprocessor feature for virtual memory, where the most recent physical to virtual address translations are cached, in the expectation that these translations are likely to be needed again soon.
vps_ceiling(5) vps_ceiling(5) (Tunable Kernel Parameters) Therefore, it is best to only raise this tunable if you know precisely the memory usage of the system. In general, increasing the variable page size on a per application basis for known applications, such as, databases which scan large amounts of data with only one page fault, is a much better practice.

Section 7 Device (Special) Files
intro(7) intro(7) NAME intro - introduction to device special files DESCRIPTION This section describes the device special files used to access HP peripherals and device drivers. The names of the entries are generally derived from the type of device being described (disk, terminal, etc.), not the names of the device special files or device drivers themselves. Characteristics of both the hardware device and the corresponding HP-UX device driver are discussed where applicable.
arp(7P) arp(7P) NAME arp - Address Resolution Protocol DESCRIPTION ARP is a protocol used to dynamically map between DARPA Internet and hardware station addresses. It is used by all LAN drivers. A aA ARP caches Internet-to-hardware station address mappings.

autochanger(7) autochanger(7) repositions two different units of media. One unit of media is moved from the element specified by the source field to the element specified by the first_destination field. A second unit of media is moved from the element specified by the first_destination field to the element specified by the second_destination field. In an autochanger with multiple changer mechanisms, or a media staging area, an exchange occurs if the source and second_destination fields are the same.
autochanger(7) Some non-HP autochanger(7) media changer devices do not support the SIOC_INIT_ELEM_STAT and SIOC_ELEMENT_STATUS ioctls. Some older media changer devices do not support the SIOC_EXCHANGE_MEDIUM ioctl. For these devices, multiple SIOC_MOVE_MEDIUM ioctl operations may be used to accomplish the same results, provided a suitable temporary element address may be found. SEE ALSO insf(1M), mknod(1M), scsictl(1M), ioctl(2), scsi(7), scsi_ctl(7).
blmode(7) blmode(7) NAME blmode - terminal block mode interface DESCRIPTION This terminal interface adds functionality to the current termio (7) functionality to allow for efficient emulation of MPE terminal driver functionality. Most importantly, it adds the necessary functionality to support block mode transfers with HP terminals. The block mode interface only affects input processing and does not affect write requests. Write requests are always processed as described in termio (7).
blmode(7) A bA blmode(7) CBTRIG1C (DC1) is the initial trigger character sent to the terminal at the beginning of a read request. CBTRIG2C (DC1) is the secondary trigger character sent to the terminal after the alert character has been received. CBALERTC (DC2) is the alert character sent by the terminal in response to the first trigger character. It signifies that the terminal is ready to send the data block. The alert character can be escaped by preceding it with a backslash ( \ ).
blmode(7) blmode(7) On systems that support process group control, ioctl requests are restricted from use by background processes, unless otherwise noted for a specific request. An attempt to issue an ioctl request from a background process causes the process to block and may cause a SIGTTOU signal to be sent to the process group.
cent(7) cent(7) (Workstations Only) NAME cent - Centronics-compatible interface DESCRIPTION cent is a simple, widely used communication protocol most commonly associated with printers, plotters and scanners. It is an eight-bit parallel data interface with additional control signals from the host computer, and status signals from the peripheral. A cA The cent interface driver does no character processing; that is, it does not interpret the data being transferred between computer and peripheral.
clone(7) clone(7) NAME clone - opens a major and minor device pair on a STREAMS driver DESCRIPTION The clone driver is a "pass through" device driver that allows other drivers to select unique minor device numbers on each open(). In effect, the driver passes an open operation through to the other driver. This mechanism allows for multiple instantiations of a driver, each with a different minor number, through a single device file.
console(7) console(7) NAME console, systty, syscon - system console interface DESCRIPTION /dev/console provides a termio interface to the device configured as the system console. The init (1M) man page discusses the uses of /dev/systty and /dev/syscon. Output data normally sent to the console, either through /dev/console or generated by a kernel printf, may be redirected to another terminal or pseudo-terminal device through the TIOCCONS ioctl(). See termio (7) for details.
ddfa(7) ddfa(7) NAME ddfa - Data Communications and Terminal Controller (DTC) Device File Access (DDFA) software DESCRIPTION The Data Communications and Terminal Controller (DTC) Device File Access (DDFA) software allows access from HP-UX system utilities and user applications to terminal servers using standard HP-UX structures. DDFA provides an interface to remote LAN-connected terminal server ports that is similar to the interface for local directly-connected ports.
ddfa(7) ddfa(7) Configuring the Port Configuration Files A port configuration file is used to configure individual terminal server ports. A master port configuration file is /usr/examples/ddfa/pcf. In practice, it is renamed for each port that needs different configuration values and the values are altered appropriately for the device attached to the port. It is recommended that a directory be created to hold the port configuration files and the dp file.
ddfa(7) ddfa(7) HUPCL flag DDFA does not support the hanging up of modem signals on the last close of the device file. If the modem signals used on the DTC drop, the connection is closed. CLOCAL flag Not supported. c_flags IENQACK not supported. OFILL, OFDEL, NLDLY, CRDLY, TABDLY, BSDLY, FFDLY not supported by Telnet port identification software. BINARY mode flags Part of static configuration is done in DTC Manager by selecting binary mode.

diag2(7) diag2(7) NAME diag2 - interface for diagnostic logging and interface to processors DESCRIPTION diag2 is used by hardware monitors and tools within the Support Tools Manager (STM), to interact with processor hardware via Processor Dependent Code (PDC). Without diag2, support tools for processors will not be able to operate.
disk(7) disk(7) NAME disk - direct disk access DESCRIPTION This entry describes the actions of HP-UX disk drivers when referring to a disk as either a block-special or character-special (raw) device. Device File Naming Conventions Standard disk device files are named according to the following conventions: Block-mode Devices /dev/dsk/cxtydn[sm] Character-mode Devices /dev/rdsk/cxtydn[sm] where component parts of the filename are constructed as follows: A dA c Required.
disk(7) disk(7) size is a hardware-dependent value that can be queried with the DIOC_DESCRIBE ioctl call, which is described below. In addition to reading and writing data, the character-special file interface can used to obtain device specific information and to perform special operations. These operations are controlled through use of ioctl calls. Details related to these ioctls are contained in . The DIOC_DESCRIBE ioctl can be used to obtain device specific identification information.
dlpi(7) dlpi(7) NAME dlpi - data link provider interface DESCRIPTION This manual page gives a brief description on DLPI (the data link provider interface) and how to interface with the set of API’s that are provided by DLPI. HP-UX DLPI serves as a Layer 2 (Data Link Layer) of an OSI architecture. DLPI serves as an interface between LAN device drivers and DLPI users. DLPI is intended for use by experienced network users only. HP-UX DLPI has two broader sets of interface.

[EIO] I/O error (e.g., media defect or device communication problem). WARNINGS Media removal and/or replacement while the device is open is not supported. A floppy disk containing a mounted file system should not be removed prior to being unmounted. Removal of floppy disks containing mounted file systems is likely to result in file system errors, and system panics.
framebuf(7) framebuf(7) NAME framebuf - information for raster frame-buffer devices SYNOPSIS #include DESCRIPTION Frame-buffer devices are raster-based displays. These devices use memory-mapped I/O to obtain much higher performance than possible with tty-based graphic terminals. Frame-buffer devices can be accessed directly using this interface, although access through the STARBASE libraries is recommended (see starbase (3G)).
framebuf(7) framebuf(7) GCMAP command is issued (see below) are the correct addresses returned so the user can access the frame-buffer regions directly using the returned addresses. GCID Provide a device identification number. The parameter is defined as int *arg ;. The information returned when using this command is a subset of the information provided by GCDESCRIBE, and is provided here for backward compatibility only. GCON, GCOFF Turn graphics on or off.
framebuf(7) framebuf(7) sigsetmask (2)) before a GCUNLOCK request is made will not have any effect on these blocked signals. The signals are not blocked until the lock is actually acquired, and might be received while still awaiting the lock. The signal SIGTSTP is also blocked whether or not it is being caught. The signals SIGTTIN and SIGTTOU are also blocked on frame-buffer devices where the ITE does not output to the device while it is locked. See DEPENDENCIES below.
framebuf(7) framebuf(7) The skipcount parameter allows the user to refresh a portion of a window image that the user has stored in memory for those cases where only a portion of the image needs to be refreshed. The window image is then a superset of the rectangle being updated, and might thus have different dimensions. The skipcount specifies the portion of the row in the larger window image that is excluded from the rectangle.
framebuf(7) framebuf(7) S9000_ID_98720 S9000_ID_98730 S9000_ID_98550 For the HP A1047A Interface Card, the fields of the crt_dma_info structure have the following restrictions: mem_addr fb_addr length skipcount 32-byte aligned 16-byte aligned non-zero multiple of 32 0 ERRORS A fA [EAGAIN] The operation would result in suspension of the calling process, but the request was either GCLOCK_NOWAIT or GCLOCK_BLOCKSIG_NOWAIT.
gang_sched(7) gang_sched(7) NAME gang_sched - Gang Scheduler DESCRIPTION The gang scheduler permits a set of MPI (Message Passing Interface) processes, or multiple threads from a single process, to be scheduled concurrently as a group. Gang scheduling is enabled and disabled by setting the MP_GANG environment variable to ON or OFF. The gang scheduling feature can significantly improve parallel application performance in loaded timeshare environments that are oversubscribed.
gang_sched(7) gang_sched(7) Gangs are scheduled for a single time-slice. The time-slice is the same for all threads in the system, whether gang-scheduled or not. When a single gang executes on a system, the gang’s threads are assigned to processors in the system and are not migrated to different processors. In an oversubscribed system with multiple gangs, all gangs are periodically moved in order to give an equalized percentage of CPU time to each of the different threads.
gang_sched(7) gang_sched(7) • If a gang-scheduled process is selected to be swapped out, the process will not be gang-scheduled when it is swapped back in. • Realtime processes are not gang-scheduled. • Gang scheduling is only supported for processes with timeshare scheduling policies. • When a gang-scheduled process contains the maximum number of threads (or the maximum number of processes, for MPI applications), threads or processes created after this point are not scheduled as part of the gang.

inet(7F) inet(7F) NAME inet - Internet protocol family SYNOPSIS #include #include DESCRIPTION The internet protocol family is a collection of protocols layered on top of the Internet Protocol (IP) network layer, which utilizes the internet address format. The internet family supports the SOCK_STREAM and SOCK_DGRAM socket types. Addressing Internet addresses are four byte entities. The include file defines this address as the structure struct in_addr.
iomap(7) iomap(7) NAME iomap - physical I/O address mapping SYNOPSIS #include DESCRIPTION The iomap mechanism allows the mapping (thus direct access) of physical I/O addresses into the user process address space. For PA-RISC machines, the physical I/O address space begins at 0xf0000000 and extends to 0xffffffff. The special (device) files for iomap devices are character special files using the dynamic major number allocation scheme.
iomap(7) iomap(7) [ENODEV] Read and write calls are unsupported. [ENXIO] No such device at the address specified by the minor number. [ENOSPC] Required resources for mapping could not be allocated. [ENOTTY] Inappropriate ioctl request for this device type; fildes is not a file descriptor for an iomap device file. EXAMPLES Consider the following code fragment: #include ... int fildes; void *addr; ...
IP(7P) IP(7P) NAME IP - Internet Protocol SYNOPSIS #include #include s = socket(AF_INET, SOCK_DGRAM, 0); DESCRIPTION IP is the network-layer protocol used by the Internet protocol family. It encapsulates TCP and UDP messages into datagrams to be transmitted by the network interface. Normally, applications do not need to interface directly to IP.
IP(7P) IP(7P) IP_DROP_MEMBERSHIP allows the system to leave a multicast group. For example: struct ip_mreq mreq; mreq.imr_multiaddr.s_addr = net_addr("224.1.2.3"); mreq.imr_interface.s_addr = INADDR_ANY; setsockopt(s, IPPROTO_IP, IP_DROP_MEMBERSHIP, &mreq, sizeof(mreq)); The system remains a member of the multicast group until the last socket that joined the group is closed or has dropped membership in the group.
IP(7P) IP(7P) [EOPNOTSUPP] The socket type is not SOCK_DGRAM. [ETOOMANYREFS] An attempt to join more than IP_MAX_MEMBERSHIPS multicast groups on a socket. AUTHOR The socket interfaces to IP were developed by the University of California, Berkeley. Multicast extensions were developed by the Stanford University. SEE ALSO bind(2), getsockopt(2), recv(2), send(2), socket(2), inet(7F).
IPv6(7P) IPv6(7P) NAME IPv6, ipv6, ip6 - Internet Protocol Version 6 SYNOPSIS #include #include s = socket(AF_INET6, SOCK_DGRAM, 0); s = socket(AF_INET6, SOCK_STREAM, 0); DESCRIPTION IPv6 is the next generation network-layer protocol designed to be the successor to the current Internet Protocol version 4 (IPv4). It provides the packet delivery service for TCP, UDP and ICMPv6.
IPv6(7P) IPv6(7P) new option value specified is used as the hop limit for all subsequent unicast packets sent via that socket. Valid values are in the range 0-255 (both inclusive) and the default value is 64. For example, int hoplimit = 50; setsockopt(s, IPPROTO_IPV6, IPV6_UNICAST_HOPS, &hoplimit, sizeof(hoplimit)); This option can be used with getsockopt() (see getsockopt (2)) to determine the hop limit value the system will use for subsequent unicast packets sent via that socket.
IPv6(7P) IPv6(7P) in6_pktinfo structure and it is defined in as: struct in6_pktinfo { struct in6_addr ipi6_addr; uint32_t ipi6_ifindex; }; By default this option is disabled. IPV6_RECVHOPLIMIT (boolean) When this option is enabled, inbound packet’s hoplimit is returned as ancillary data by recvmsg(). For example, int on = 1; setsockopt(s, IPPROTO_IPV6, IPV6_RECVHOPLIMIT, &on, sizeof(on)); By default this option is disabled.
IPv6(7P) IPv6(7P) ERRORS One of the following errors may be returned when a socket operation fails. [EADDRINUSE] The specified multicast group has been joined already. [EADDRNOTAVAIL] The specified IPv6 address is not a local interface address or there is no route for the specified multicast address or the specified multicast group has not been joined.

kmem(7) kmem(7) NAME kmem - perform I/O on kernel memory based on symbol name. SYNOPSIS #include int ioctl(int kmemfd , int command , void *rks ); DESCRIPTION When used with a valid file descriptor for /dev/kmem (kmemfd), ioctl can be used to manipulate kernel memory. The specifics of this manipulation depend on the command given as follows: MIOC_READKSYM Read mirk_buflen bytes of kernel memory starting at the address for mirk_symname into mirk_buf .
kmem(7) kmem(7) [ENAMETOOLONG] modname is greater than MODMAXNAMELEN characters long, or symname is greater that MAXSYMNMLEN characters long. SEE ALSO getksym(2), ioctl(2), ioctl(5).
lan(7) lan(7) NAME lan - network I/O card access information DESCRIPTION This manual entry gives a brief description on how to access the LAN device driver at Layer 2 (Data Link Layer) of the OSI architecture. The LAN device driver controls the various LAN interface cards (e.g, Ethernet/IEEE 802.3, FDDI, Token Ring) at Layer 1 (Physical Layer). The Data Link Provider Interface (DLPI) is the supported method for accessing the LAN device driver at Layer 2.
ldterm(7) ldterm(7) NAME ldterm - standard STREAMS terminal line discipline module SYNOPSIS #include #include #include #include #include #include #include int ioctl( fd, I_PUSH, "ldterm"); DESCRIPTION ldterm is a STREAMS module that supplies the line discipline for streams-based terminal or pseudoterminal device drivers.
ldterm(7) ldterm(7) It generates echo characters and places them in the output buffer to be sent downstream to the write queue. While processing incoming data, it scans for START and STOP characters and sends M_START, M_STOP messages downstream to the write queue, if needed. If the total number of buffered input characters is more than the high-water mark and IXOFF is set, the read put routine sends an M_STOPI message downstream.
ldterm(7) ldterm(7) Write-side Behavior ldterm processes the following STREAMS messages on its output stream. Messages not listed here are simply forwarded downstream. M_FLUSH The write put routine flushes the write queue and discards any buffered output data. Then, it forwards the message downstream. M_DATA The write service routine processes the data according to the POSIX 1003.1 specification output flags.
ldterm(7) ldterm(7) TCGETA This command get the old System V termio information. The ldterm module converts the message to a POSIX termios M_IOCTL message, then forwards the message with the TCGETS command. The original I/O control command and M_IOCTL message are stored to be used on M_IOCACK. When it receives the matching M_IOCACK message, the ldterm module processes it as for a TCGETS command, then converts the POSIX termios information into the System V termio information and replies.
ldterm(7) ldterm(7) TIOCSETD The ldterm module does nothing but reply to this command. In a BSD system, the command is used to set the current line discipline type. It does not have much meaning in a STREAMS environment, because line discipline modules are changed by popping the current module from the stream and pushing a different one onto the stream. TIOCGETD In a BSD system, this command is used to get the current line discipline type. The command does not have much meaning in a STREAMS environment.
ldterm(7) ldterm(7) to an tchars structure via where the information is returned. TIOCSLTC This command sets the ltchars information defined in . The ldterm module converts the message to a POSIX termios M_IOCTL message. Then, it forwards the POSIX termios M_IOCTL message with a corresponding POSIX termios command (i.e. TCSETS). The original I/O control command and M_IOCTL message are stored for use on M_IOCACK.
lp(7) lp(7) (Series 800 Only) NAME lp - line printer SYNOPSIS #include Remarks: This manual entry applies only to a certain group of printers. For Series 800 systems, it applies to printers controlled by the device driver lpr2. It does not apply to any printers on Series 700 systems. DESCRIPTION This section describes capabilities provided by many line printers supported by various versions of the HP-UX operating system.

lvm(7) lvm(7) NAME lvm - Logical Volume Manager (LVM) DESCRIPTION The Logical Volume Manager (LVM) is a subsystem for managing disk space. The HP LVM subsystem offers value-added features, such as mirroring (with the optional HP MirrorDisk/UX software), high availability (with the optional HP ServiceGuard software), and striping, that enhance availability and performance.
lvm(7) lvm(7) EXAMPLES The basic steps to take to begin using LVM are as follows: • Identify the disks to be used for LVM. • Create an LVM data structure on each identified disk (see pvcreate (1M)). • Collect all the physical volumes to form a new volume group (see vgcreate (1M)). • Create logical volumes from the space in the volume group (see lvcreate (1M)). • Use each logical volume as if it were a disk section (create a file system, or use for raw access).
mem(7) mem(7) NAME mem - main memory DESCRIPTION mem is a special file that is an image of the main memory of the computer. It may be used, for example, to examine and patch the system. Byte addresses in mem are interpreted as physical memory addresses. References to non-existent locations cause errors to be returned. File kmem is the same as mem except that kernel virtual memory rather than physical memory is accessed.
modem(7) modem(7) NAME modem - asynchronous serial modem line control SYNOPSIS #include DESCRIPTION This section describes the two modes of modem line control and the three types of terminal port access. It also discusses the effect of the bits of the termio structure that affect modem line control. The modem related ioctl (2) system calls are discussed at the end of the document.
modem(7) modem(7) The call-in type of access is used when the connection is expected to be established by an incoming call. This is the type that would be used by getty (1M) to accept logins over a modem. When an open is issued to such a file, the driver may wait for an incoming call and will then raise the CONTROL based on the current mode (see below) of the port. When the port is closed, the driver may or may not lower the CONTROL depending on the HUPCL bit.
modem(7) modem(7) When a port is in simple mode, the driver will normally control the modem lines. However, the user is allowed to change the setting of the CONTROL (see Modem ioctls below). Terminal port access interlock An interlock mechanism is provided between the three access types of terminal files.

mt(7) mt(7) NAME mt - magnetic tape interface and controls for stape and tape2 DESCRIPTION This entry describes the behavior of HP magnetic tape interfaces and controls, including reel-to-reel, DDS, QIC, 8mm, and 3480 tape drives. The files /dev/rmt/* refer to specific raw tape drives, and the behavior of each given unit is specified in the major and minor numbers of the device special file. Naming Conventions There are two naming conventions for device special files.
mt(7) mt(7) DLT Selects one of the known DLT formats; can be used to specify DLT42500_24, DLT42500_56, DLT62500_64, DLT81633_64, or DLT85937_52, as required. QIC Selects one of the known QIC formats; can be used to specify QIC11, QIC24, QIC120, QIC150, QIC525, QIC1000, QIC1350, QIC2100, QIC2GB, or QIC5GB, as required. D8MM Selects one of the known 8MM formats; can be used to specify D8MM8200 or D8MM8500, as required.
mt(7) mt(7) During a read, the record size is passed back as the number of bytes read, up to the buffer size specified. Since the minimum read length on a tape device is a complete record (to the next record mark), the number of bytes ignored (for records longer than the buffer size specified) is available in the mt_resid field of the mtget structure via the MTIOCGET call of ioctl (2). Current restrictions require tape device application programs to use 2-byte alignment for buffer locations and I/O sizes.

ndp(7P) ndp(7P) NAME NDP - Neighbor Discovery Protocol DESCRIPTION NDP is a protocol used by hosts and routers to: 1. Find the link-layer address of the neighbors known to be attached to the same link. 2. Find the neighboring routers that are willing to forward packets on their behalf. 3. Actively keep track of which neighbors are reachable and which are not. 4. Search for alternate routers when the path to a router fails. To accomplish the above mentioned tasks, NDP, defines the following processes: 1.
ndp(7P) • ndp(7P) Processing router advertisements. This rule discusses what actions should be taken on receipt of router advertisements. • Timing out prefixes and default routers. Whenever routers send router advertisements they include the lifetime of the router as well as the prefixes that they advertise. NDP specifies what actions the host should take when these lifetimes expire.
ndp(7P) ndp(7P) b. If a host with the specified IPv6 address is present in the network, it will reply this solicitation with a Neighbor Advertisement Message. c. On receiving the Neighbor Advertisement the node will search for an entry in the neighbor cache for the sender’s IPv6 address. A new entry is created in the neighbor cache and the reachability flag is set to REACHABLE. Once the Address resolution is completed, neighbor unreachability detection will be performed.
nfs(7) nfs(7) NAME nfs, NFS - network file system DESCRIPTION The Network File System (NFS) allows a client node to perform transparent file access over the network. By using NFS, a client node operates on files residing on a variety of servers and server architectures, and across a variety of operating systems. File access calls on the client (such as read requests) are converted to NFS protocol requests and sent to the server system over the network.
null(7) null(7) NAME null - null file DESCRIPTION Data written on a null special file is discarded. Reads from a null special file always return 0 bytes. EXAMPLES To create a zero-length file, use either of the following: cat /dev/null > file cp /dev/null file FILES /dev/null STANDARDS CONFORMANCE null: AES, SVID2, SVID3, XPG2, XPG3, XPG4, FIPS 151-2, POSIX.1, POSIX.
pckt(7) pckt(7) NAME pckt - Packet Mode module for STREAMS pty (pseudo-terminal) SYNOPSIS #include int ioctl(fd_slave, I_PUSH, "pckt"); DESCRIPTION The Packet Mode feature for STREAMS pty devices allows the user process on the master side of the pty device to be informed of state changes in the pty. To enable Packet Mode in the STREAMS pty device, the user process must push the pckt module onto the master side of the pty with a call to the STREAMS I_PUSH ioctl (2) system call.
poll(7) poll(7) NAME poll - monitor I/O conditions on multiple file descriptors SYNOPSIS #include #include
poll(7) poll(7) struct pollfd pfd[2]; int err; pfd[0].fd = fd1; pfd[0].events = POLLIN; pfd[1].fd = fd2; pfd[1].events = (POLLIN | POLLRDBAND); err = write(evpfd, pfd, sizeof(pfd)); Polling File Descriptors Polling an event port’s interest set is initiated by calling ioctl() specifying the DP_POLL request . The ioctl arg parameter is a pointer to a dvpoll structure, defined in .
poll(7) poll(7) If ioctl() returns -1, errno is set to the error condition. ERRORS The following errors are returned by the event port driver. If open() fails, errno is set to one of the following values. [EACCES] [EAGAIN] The minor number of the device file name passed to open() is not 0. Allocation of internal data structures failed due to a temporary condition. Calling open() again might succeed. [EMFILE] The maximum number of file descriptors allowed for the process is already open.
poll(7) poll(7) After the last non-blocking write succeeds, the following should be used to deregister for POLLOUT, but continue to be registered for input notifications. Note that POLLREMOVE must be used in order to remove the POLLOUT registration. struct pollfd regpfd[2]; int err; regpfd[0].fd = sd; regpfd[0].events = POLLREMOVE; regpfd[1].fd = sd; regpfd[1].

ps2(7) ps2(7) NAME ps2, ps2kbd, ps2mouse - PS/2 keyboard/mouse device driver and files SYNOPSIS #include DESCRIPTION The ps2 driver allows the use of IBM Personal System/2 (PS/2) compatible keyboards and mouse devices on Hewlett-Packard workstations equipped with PS/2 interface hardware. On systems with a single interface, PS/2 device file names use the following format: /dev/ps2_n where n represents the interface port number, ranging from 0 to 15.
ps2(7) ps2(7) If both file status flags O_NDELAY and O_NONBLOCK are clear and no data is available, the read() call blocks until data becomes available or a signal is received. If the file status flag O_NDELAY is set and no data is available, the read() call returns zero instead of blocking. If the file status flag O_NONBLOCK is set and no data is available, the read() call returns -1 with errno set to [EAGAIN] (see errno (2)). The write() system call is not supported by ps2.
ps2(7) ps2(7) PS2_ENABLE Enable a PS/2 device Transmissions from the device are enabled. This request does not use arg. Identify a PS/2 device. PS2_IDENT A value identifying the type of device is returned in the 4-byte buffer addressed by arg. The keyboard returns two bytes (arg[0]=0xAB and arg[1]=0x83). The mouse returns one byte (arg[0]=0x00). PS2_SETDEFAULT Set the device to its default (power-up) state. The device is returned to its default internal state. This request does not use arg.
ps2(7) PS2_KEY_MAKE ps2(7) Set make-only behavior for an individual key. The key code from scancode set 3 for the individual key is passed as the first byte in the character buffer addressed by arg. This request can be made when the keyboard is using any scancode set; however, it affects only the operation of scancode set 3. Because keyboards might be left in a disabled state after this request, the PS2_ENABLE request should be performed after PS2_KEY_MAKE.
ps2(7) ps2(7) ioctl() request. The arg parameter is not used. PS2_REPORT Obtain a prompt mode mouse report. This request polls the mouse, obtaining a three-byte report returned in the character buffer addressed by the arg parameter.

ptem(7) ptem(7) NAME ptem - STREAMS pty (pesudo-terminal) Emulation module SYNOPSIS #include int ioctl(fd_slave, I_PUSH, "ptem"); DESCRIPTION ptem is a STREAMS module that emulates a terminal when used in conjunction with ldterm (STREAMS line discipline) and pts (STREAMS slave pty driver). The ptem module normally sits above pts and below ldterm.
ptem(7) ptem(7) upstream with the jwinsize structure. If the values are zero, ptem sends an M_IOCNAK message upstream. • When an M_IOCTL message of type TIOCGWINSZ is received on its write queue and if the values in the winsize structure in ptem are not zero, ptem sends an M_IOCACK message upstream with the winsize structure. If the values are zero, ptem sends an M_IOCNAK message upstream.
ptm(7) ptm(7) NAME ptm - STREAMS master pty (pseudo-terminal) driver SYNOPSIS #include #include #include int open("/dev/ptmx", O_RDWR); DESCRIPTION A pseudo-terminal (pty) consists of a tightly-coupled pair of character devices, called the master device and slave device.
ptm(7) ISPTM ptm(7) Determines whether the file descriptor is that of an open master device. On success, it returns the major and minor number (type dev_t) of the master device which can be used to determine the name of the corresponding slave device. On failure, it returns −1 with errno set to [EINVAL]. ISPTM on HP-UX can return valid device number with negative value. For example, with major number of the STREAMS pty master being 0x9c, ICPTM will return 0x9C000000 which is a negative number.
pts(7) pts(7) NAME pts - STREAMS slave pty (pseudo-terminal) driver SYNOPSIS #include #include #include int open("/dev/pts/N", O_RDWR); DESCRIPTION A pseudo-terminal (pty) consists of a tightly-coupled pair of character devices, called the master device and slave device.
pts(7) pts(7) slave = ptsname(fd_master); fd_slave = open(slave, O_RDWR); ioctl(fd_slave, I_PUSH, "ptem"); ioctl(fd_slave, I_PUSH, "ldterm"); AUTHOR pts was developed by HP and OSF. FILES /dev/ptmx /dev/pts/N Streams pty master clone device Streams pty slave devices (0 <= N < NSTRPTY), where NSTRPTY is a kernel tunable parameter which can be changed via SAM (see sam(1M)).
pty(7) pty(7) NAME pty - pseudo terminal driver DESCRIPTION The pty driver provides support for a device-pair termed a pseudo terminal. A pseudo terminal is a pair of character devices, a master device and a slave device. The slave device provides to application processes an interface identical to that described in termio (7). Unlike all other devices that provide the interface described in termio (7), the slave device does not have a hardware device behind it.
pty(7) pty(7) default, termio processing is enabled. termio processing refers to processing of input and output described by termio (7) (such as tab expansion), as well as the processing of the ioctl() requests described by termio (7). When disabled, all input and output data is passed through the pty without modification. Issuing a TIOCTTY ioctl() request flushes all data buffered in the pseudo terminal and releases any processes blocked waiting for data.
pty(7) pty(7) the slave side. In normal usage, writing data is like typing the data as a line on a terminal; writing zero bytes is equivalent to typing an end-of-file character (that is, the EOF character as defined in termio (7)). The data read by the slave side is identical to the data written on the master side. Data written on the slave side and read on the master side with TIOCREMOTE enabled is still subject to the normal termio (7) processing.
pty(7) pty(7) handshake is done automatically. Trapping occurs in two forms that are identified by the ioctl() requests that enable or disable them — TIOCTRAP and TIOCMONITOR. These two forms are distinguished by the types of requests they affect and by the capabilities they provide. Trapping open() and close() requests is enabled or disabled by TIOCTRAP. Trapping ioctl() requests not defined by termio (7) are enabled or disabled by TIOCTRAP.
pty(7) pty(7) errno_error can be used to return an error for trapped slave pty open() requests. See the discussion of the TIOCSMODES ioctl() for further information on open error mode. return_value The success value (initialized to zero) returned by ioctl() on the slave side when errno_error is not set. When the ioctl() argument received on the slave side is not a pointer, its value is stored as four bytes retrievable with an ioctl() request to the master side equal to argget.
pty(7) pty(7) trapping is enabled if the int addressed by arg is nonzero and disabled if the int addressed by arg is zero. By default, TIOCMONITOR trapping is disabled. TIOCMONITOR works in series with TIOCTTY; that is, the TIOCMONITOR trapping must be enabled and TIOCTTY must be enabled for termio ioctl() requests to be trapped by TIOCMONITOR. TIOCMONITOR trapping can be enabled or disabled regardless of the state of TIOCTTY.
pty(7) pty(7) whose open() or ioctl() request is trapped. Signals are postponed if they would otherwise cause the process to jump to an installed signal handler. Signals are not postponed if they would otherwise cause the process to abort or if they are being ignored. When the server process completes the handshake by means of the TIOCREQSET ioctl() request, the process returns to the calling program and any pending signals are then acted upon.
pty(7) pty(7) WARNINGS The slave side cannot indicate an end-of-file condition to the master side. When using TIOCREMOTE, a single write() request to the master side of greater than 256 bytes may result in multiple smaller records being read from the slave side instead of only one record. AUTHOR pty was developed by the University of California, Berkeley.
random(7) random(7) NAME random, urandom, rng - strong random number generator SYNOPSIS #include DESCRIPTION The character special files /dev/random and /dev/urandom provide an interface to the kernelresident random number generator, rng. A read() from /dev/random is potentially blocking, as compared to a read from /dev/urandom which is always nonblocking. Data from /dev/urandom can potentially have lower entropy than data from /dev/random.
random(7) random(7) Specific Information About /dev/urandom To address the limited random data collection rate problem, the /dev/urandom device is strictly nonblocking. The /dev/urandom holding buffer is regularly updated with random data, yet a high number of reads can decrease the entropy in its holding buffer. Under this conditions, the entropy of the data from /dev/urandom will be slightly lower that the one from /dev/random, yet /dev/urandom can still be considered a good source of random numbers.
routing(7) routing(7) NAME routing - system support for local network packet routing DESCRIPTION The network facilities for HP-UX provide general packet routing support. Routing table maintenance is handled by application processes. A routing table consists of a set of data structures used by the network facilities to select the appropriate remote host or gateway when transmitting packets.

scsi(7) scsi(7) device control (see scsi_ctl (7)). Drivers that support only devices which have no meaningful size may not support the SIOC_CAPACITY 32 ioctl. Total device size in bytes may exceed 2 −1 for some devices. DEPENDENCIES sdisk/schgr/sflop/stape The SIOC_EXCLUSIVE ioctl may be used to obtain and release exclusive access. Exclusive access, which prevents simultaneous access by other applications, is required for some operations and may be desirable in other circumstances.
scsi_ctl(7) scsi_ctl(7) NAME scsi_ctl - SCSI pass-through driver DESCRIPTION SCSI devices are controlled by a device-specific driver, when one exists. Device-specific drivers, such as those for SCSI direct access (disk) and sequential access (tape) devices, coordinate device and driver states to accomplish correct logical device behavior. The scsi_ctl pass-through driver enables use of SCSI devices and commands not normally supported by these device-specific drivers.
scsi_ctl(7) scsi_ctl(7) At power-up and after being reset, all parallel SCSI devices and hosts communicate using eight-bit data transfers. A SCSI target and host pair may agree to use sixteen-bit (wide) data transfers to increase I/O performance. To make use of wide data transfers, a SCSI target and host must negotiate to determine a mutually acceptable data transfer width parameter.
scsi_ctl(7) scsi_ctl(7) xfer_rate, max_width, max_reqack_offset, max_xfer_rate fields only apply to parallel SCSI. Bus communication parameters may be managed by use of the SIOC_GET_BUS_PARMS, SIOC_SET_BUS_LIMITS, and SIOC_GET_BUS_LIMITS ioctls to any associated LUN. The SIOC_GET_BUS_PARMS ioctl indicates the current bus communication parameter values.

scsi_disk(7) scsi_disk(7) value disables write verification. The value 1 enables write verification. Although write verification is primarily intended for optical media, some systems may support write verification on normal disk devices. The SIOC_VERIFY ioctl verifies that a media area contains valid data (that is, data that has been correctly written). Verified media will not cause I/O errors when reading is attempted. The media area to be verified is specified via the start_lba and block_cnt fields.
scsi_tape(7) scsi_tape(7) (Series 700 Only) NAME scsi_tape - SCSI sequential access (tape) device driver DESCRIPTION SCSI sequential-access (tape) devices store a sequence of data blocks. Data can be read and written using either fixed or variable sized block mode. If supported by the device, variable sized block mode is normally used (even when all blocks are the same size). Fixed sized block mode is generally only used for tape devices which do not support variable sized blocks.

sioc_io(7) sioc_io(7) NAME sioc_io - SCSI pass-through interface DESCRIPTION SCSI devices are controlled by a device-specific driver, when one exists. Device-specific drivers, such as those for SCSI direct access (disk) and sequential access (tape) devices, coordinate device and driver states to accomplish correct logical device behavior. The sioc_io pass-through interface enables the use of SCSI devices and commands not normally supported by these device-specific drivers.

slp_syntax(7) slp_syntax(7) NAME slp_syntax - SLP Service Type Syntax DESCRIPTION The SLP API expects service type information to be passed while querying for SLP service information and also while registering and deregistering services. The SLP API accepts service type information in URL format also. The service type string contains the following information. Name of the service type. Naming Authority responsible for the service name. The service type string is of the form: service :abstract-type.
slp_syntax(7) slp_syntax(7) service:chat.superchat://chat.superchat.com;auth=ldap SLP requires you to use Service URLs. API functions will return SLP_PARSE_ERROR if you do not. Service URLs are required because the SLP API designers do not allow the service-type to be passed in as a parameter to the SLPDeReg() call. Without the service-type, SLPDeReg() does not allow the caller to distinguish between services of varying types that were registered with the same standard URL.
socket(7) socket(7) NAME socket - interprocess communications DESCRIPTION Sockets are communication endpoints that allow processes to communicate either locally or remotely. They are accessed by means of a set of system calls (see socket (2)). The following ioctl() requests are defined in (see ioctl (2)): FIOSNBIO If the int with the address arg is non-zero, the socket is put into non-blocking mode. Otherwise, the socket is put into blocking mode. Blocking mode is the default.
socket(7) socket(7) DEPENDENCIES AF_CCITT Only Only the FIOSNBIO, FIONREAD, SIOCGPGRP, and SIOCSPGRP ioctl() requests are defined for af_ccitt sockets. AUTHOR socket was developed by the University of California, Berkeley. SEE ALSO fcntl(2), getsockopt(2), ioctl(2), socket(2).
streamio(7) streamio(7) NAME streamio - STREAMS ioctl commands SYNOPSIS #include #include int ioctl(int fildes , int command, ... /* arg */); DESCRIPTION STREAMS ioctl commands are a subset of the ioctl() system calls which perform a variety of control functions on streams. fildes is an open file descriptor that refers to a stream. command determines the control function to be performed as described below. arg represents additional information that is needed by this command.
streamio(7) streamio(7) the databuf strbuf structure must be set to the number of bytes of data information to be sent with the message or zero if no data part is to be sent. flags specifies the type of message to be created. An ordinary (non-priority) message is created if flags is set to 0, a high priority message is created if flags is set to RS_HIPRI. For normal messages, I_FDINSERT will block if the stream write queue is full due to internal flow control conditions.
streamio(7) streamio(7) value on the system. The default is fifteen seconds. I_GETSIG Returns the events for which the calling process has registered to receive a SIGPOLL signal. Events are returned as in arg bitmask as defined for the I_SETSIG command. I_GRDOPT Returns the current read mode setting in an int pointed to by the argument arg. Read modes are described in read (2).
streamio(7) streamio(7) The I_PEEK returns a 1 if a message was retrieved, and returns a value of 0 (zero) if no message was found; it does not wait for a message. Upon successful completion, ctlbuf specifies control information in the control buffer, databuf specifies data information in the data buffer, and options contains RS_HIPRI or 0 (zero).
streamio(7) streamio(7) I_SETCLTIME Lets the user process set the time that the stream head delays when the stream is closing and the write queues contain data. The arg parameter contains a pointer to the number of milliseconds to delay, rounded up to the nearest legal value on the system. The default time is 15 seconds. Before STREAMS modules and drivers are closed, the stream head delays for the specified amount of time. This allows the data on the write queues to drain.
streamio(7) streamio(7) Message-nondiscard mode. RMSGN Setting both RMSGD and RMSGN is an error. RMSGD and RMSGN override NORM. In addition, treatment of control messages by the stream head may be changed by setting the following flags in arg: I_STR RPROTNORM Fail read with EBADMSG if a control message is at the front of the stream head read queue. This is the default behavior. RPROTDAT Deliver the control portion of a message as data when a user issues read.
streamio(7) streamio(7) ERRORS A STREAMS ioctl command fails without performing the function and with errno set to [EINVAL] if: • The stream referred to by fildes is linked below a multiplexing driver. • The command parameter is not a valid value for the stream. In addition, if any of the following conditions occur, the STREAMS ioctl commands return the corresponding value: I_ATMARK [EINVAL] arg has an illegal value. I_CANPUT [EINVAL] arg has an illegal value.
streamio(7) streamio(7) [EINVAL] The bi_pr parameter value exceeds the maximum band, or the bi_option parameter is not FLUSHR, FLUSHW, or FLUSHRW. I_GETBAND [ENODATA] No message exists on the stream head read queue. I_GETSIG [EINVAL] User process is not registered to receive the SIGPOLL signal. [EFAULT] arg points outside the allocated address space. I_GRDOPT [EFAULT] arg is pointing outside the allocated address space.
streamio(7) streamio(7) [EINVAL] The file referred to by arg is not a stream or is already linked under a multiplexing driver. [EINVAL] The link operation would cause a "cycle" in the resulting multiplexing configuration. In other words, the driver referred to by arg is linked into the configuration at multiple places. I_POP [EINVAL] There are not modules in the stream. [ENXIO] Error value returned by the module being popped. [ENXIO] A hangup was received on fildes .
streamio(7) streamio(7) [EAGAIN] A data structure to store the signal request could not be allocated. I_SRDOPT [EINVAL] arg contains an illegal value. I_STR [EINVAL] The ic_len field is less than 0 (zero) bytes or larger than the maximum allowable size of the data part of a message (ic_dp). [EINVAL] The ic_timeout field is less than −1. [EFAULT] arg points, or the buffer area specified by ic_dp or ic_len is, outside the allocated address space.
strlog(7) strlog(7) NAME strlog - STREAMS log driver DESCRIPTION The STREAMS log driver allows user-level processes and STREAMS drivers and modules to perform error logging and event tracing. These tasks are done via a user interface and a kernel interface. Further, the STREAMS log driver delivers error logging and event tracing messages to the Network Tracing and Logging Facility (NetTL) (see nettl (1M), netfmt (1M), and nettlconf (1M)).
strlog(7) strlog(7) User Interface User processes access the log driver with an open() call to /dev/strlog. Each open to the device will obtain a separate stream. After a process opens /dev/strlog, it indicates whether it is an error logger or trace logger.
strlog(7) strlog(7) if (flags & SL_WARN) if (flags & SL_NOTE) otherwise ====> ====> ====> WARNING INFORMATIVE ERROR all messages ====> INFORMATIVE else As a default, only DISASTER and ERROR messages are logged. This setting can be altered by the nettl command or the nettlconf command (see nettl (1M) and nettlconf (1M)). The STREAMS subsystem ID used by NetTL is STREAMS. The messages logged by NetTL facility can be formatted to a readable form by the netfmt command (see netfmt (1M)).
strlog(7) strlog(7) control.len = control.maxlen = sizeof(log); control.buf = (char *)&lc; data.len = data.maxlen = strlen(warning); data.buf = warning; lc.level = 2; lc.flags = SL_FATAL|SL_CONSOLE; putmsg(logfd, &control, &data, 0); The following examples illustrate how to use the NetTL facility for the STREAMS. See nettl (1M), netfmt (1M), nettlconf (1M) for the general NetTL usage. The STREAMS subsystem ID used by NetTL is STREAMS. The netfmt accepts a filter configuration file as a command argument.
sttyv6(7) sttyv6(7) NAME stty - terminal interface for Version 6/PWB compatibility REMARKS These facilities are included to aid in conversion of old programs, and should not be used in new code. Use the interface described in termio (7). Note that these conversions do not work for programs ported from UNIX Time-Sharing System, Seventh Edition (Version 7), because some V7 flags are defined differently.

TCP(7P) TCP(7P) NAME TCP - Internet Transmission Control Protocol SYNOPSIS #include #include #include s = socket(AF_INET, SOCK_STREAM, 0); s = socket(AF_INET6, SOCK_STREAM, 0); DESCRIPTION The TCP protocol provides reliable, flow-controlled, two-way transmission of data. It is a byte-stream protocol used to support the SOCK_STREAM socket type. TCP constructs virtual circuits between peer entities.
TCP(7P) TCP(7P) longer than the second threshold, TCP terminates the connection. The default value for this option is the current value of the ndd tunable tcp_ip_abort_cinterval. See ndd(1M) online help for details on the tcp_ip_abort_cinterval default value. If TCP_NODELAY is set, the system sends small amounts of output immediately rather than gathering them into a single packet after an acknowledgement is received.

tels(7) tels(7) NAME tels, telm - STREAMS Telnet slave (pseudo-terminal) driver, STREAMS Telnet master driver (used by telnetd only), respectively SYNOPSIS #include #include int open("/dev/pts/tN", O_RDWR); DESCRIPTION A Telnet pseudo-terminal consists of a tightly-coupled pair of character devices, called the master device and slave device.
termio(7) termio(7) NAME termio, termios - general terminal interface DESCRIPTION All HP-UX asynchronous communications ports use the same general interface, regardless of what hardware is involved. Network connections such as rlogin (see rlogin (1) use the pseudo-terminal interface (see pty (7). This discussion centers around the common features of this interface. Opening a Terminal File When a terminal file is opened, it normally causes the process to wait until a connection is established.
termio(7) termio(7) blocking the SIGTTIN signal, or the process (on systems that implement vfork separately from fork ) has made a call to vfork (2) but has not yet made a call to exec (2), or the process group of the reading process is orphaned, read() returns −1 with errno set to EIO and no signal is sent. In all other cases where the read is denied, the process group of the reading process will be sent a SIGTTIN signal.
termio(7) termio(7) When the MAX_CANON limit is reached, all characters in the current undelimited line are discarded without notice. Erase and kill processing occur when any of three special characters, the ERASE, WERASE, or KILL characters (see Special Characters ), is received. This processing affects data in the input queue that has not yet been delimited by a NL, EOF, EOL, or EOL2 character. This undelimited data makes up the current line.
termio(7) termio(7) 2. Also note that in case A ( MIN > 0, TIME > 0 ), TIME represents an inter-character timer while in case C ( MIN = 0, TIME > 0 ), TIME represents a read timer. These two points highlight the dual purpose of the MIN/TIME feature. Cases A and B (where MIN > 0 ) exist to handle burst mode activity (such as file transfer programs) where a program would like to process at least MIN characters at a time.
termio(7) termio(7) waiting, (that is, the EOF occurred at the beginning of a line) a character count of zero is returned from read(), representing an end-of-file indication. If ICANON is enabled, the EOF character is discarded when processed. If ICANON is not enabled, the EOF character is treated as a normal data character. NL (ASCII LF) special character on input and is recognized if ICANON flag is enabled. It is the line delimiter (\n).
termio(7) termio(7) The special characters are assigned their default character values when the terminal port is opened. The default values used are those specified by the System V Interface Definition, Third Edition (SVID3), except for the WERASE (Ctrl-W) and LNEXT (Ctrl-V) characters which are set to _POSIX_VDISABLE to maintain binary compatibility with previous releases of HP-UX.

The structure is defined in the header file
termio(7) termio(7) If PARMRK is set, and IGNPAR is clear, a character with a framing or parity error (other than break) is read as the three-character sequence: \377, \0, X, where X is the data of the character received in error. To avoid ambiguity in this case, if ISTRIP is clear, a valid character of \377 is read as \377, \377. If both PARMRK and IGNPAR are clear, a framing or parity error (other than break) is read as the character \0. If INPCK is set, input parity checking is enabled.
termio(7) termio(7) water mark. When ICANON is set and the input stream contains more characters between line delimiters than the high water mark allows, there is no guarantee that IXOFF can prevent buffer overflow and data loss, because the STOP character may not be sent in time, if at all. If IMAXBEL is set, the ASCII BEL character is echoed if the input queue overflows. Further input is not stored, but any input present in the input queue is not discarded.
termio(7) termio(7) If a form-feed or vertical-tab delay is specified, it lasts for about 2 seconds. New-line delay lasts about 0.10 seconds. If ONLRET is set, carriage-return delays are used instead of the new-line delays. If OFILL is set, two fill characters are transmitted. Carriage-return delay type 1 depends on the current column position; type 2 is about 0.10 seconds; type 3 about 0.15 seconds. If OFILL is set, delay type 1 transmits two fill characters; type 2, four fill characters.
termio(7) termio(7) If CLOCAL is set, a connection does not depend on the state of the modem status lines. If CLOCAL is clear, the modem status lines are monitored. Under normal circumstances, a call to read() waits for a modem connection to complete. However, if either the O_NDELAY or the O_NONBLOCK flags are set or CLOCAL is set, the open() returns immediately without waiting for the connection.
termio(7) termio(7) When ICANON is set, canonical processing is enabled. This enables the erase and kill edit functions, and the assembly of input characters into lines delimited by NL, EOF, EOL and EOL2 as described in Canonical Mode Input Processing. Furthermore, the following echo functions are possible. If ECHO and ECHOE are set, the ERASE and WERASE characters are echoed as the three-character ASCII sequence BS SP BS, which clears the last character or word from the CRT screen.

termio(7) TCFLSH termio(7) If arg is 0, flush the input queue; if 1, flush the output queue; if 2, flush both the input and output queues. If any other value is given for arg, the call returns −1 with errno set to [EINVAL]. The tcflush() function performs the same functions (see tcflush(3C)). Sending a BREAK is accomplished by holding the data transmit line at a SPACE or logical zero condition for at least 0.25 seconds.
termio(7) termio(7) To prohibit FIOSNBIO-style non-blocking I/O from interfering with the O_NONBLOCK and O_NDELAY flags (see open (2) and fcntl (2)), the functionality of O_NONBLOCK and O_NDELAY always supersedes the functionality of FIOSNBIO-style non-blocking I/O. This means that if either O_NONBLOCK or O_NDELAY is set, the driver performs read requests in accordance with the definition of O_NDELAY or O_NONBLOCK.
termio(7) termio(7) feature is easily tcgetpgrp (3C)). implemented using the function tcgetpgrp() (see If the ioctl() call fails, it returns −1 and sets errno to one of the following values: [EBADF] fildes is not a valid file descriptor. [ENOTTY] The file associated with fildes is not the controlling terminal, or the calling process does not have a controlling terminal.
termio(7) termio(7) Terminal Size IOCTL Commands The following ioctl() system calls are used to get and set terminal size information for the terminal referenced by fildes . These ioctl() system calls use the winsize structure to get and set the terminal size information. The winsize structure, defined in
termio(7) termio(7) The general terminal interface uses a system resource known as a cblock to store data being transmitted or received through a communications port. These cblocks are continuously used and freed for reuse as data pass through the system. If too few cblocks are configured in the system, the cblock pool may be temporarily or permanently exhausted, and data loss, system hangs, or reduced system performance can result.

termiox(7) termiox(7) (HP-PB Only) NAME termiox - extended general terminal interface SYNOPSIS #include ioctl (int fildes , int request , struct termiox * arg) DESCRIPTION The extended general terminal interface supplements the termio (7) general terminal interface by adding support for asynchronous hardware flow control and local implementations of additional asynchronous features. Some systems may not support all of these capabilities because of hardware or software limitations.
termiox(7) termiox(7) (HP-PB Only) termiox Structure Related IOCTL Command The ioctl() system calls that reference the termiox structure have the form: ioctl (fildes, command, arg) struct termiox *arg; Commands using this form are: TCGETX The argument is a pointer to a termiox structure. The current terminal parameters are fetched and stored into that structure. TCSETX The argument is a pointer to a termiox structure. The current terminal parameters are set from the values stored in that structure.
timod(7) timod(7) NAME timod - STREAMS module for converting ioctl() calls into Transport Interface messages DESCRIPTION The timod module is a STREAMS module that converts ioctl() calls from a transport user supporting the Transport Interface (TI) into messages that a transport protocol provider supporting TI can consume. This allows the user to initiate certain TI functions as atomic operations. This release of HP-UX no longer automatically pushes timod whenever a t_open (3) is performed.
timod(7) timod(7) SEE ALSO ioctl(2), t_open(3), streamio(7), tirdwr(7).
tirdwr(7) tirdwr(7) NAME tirdwr - STREAMS module for reads and writes by Transport Interface users DESCRIPTION The tirdwr module is a STREAMS module that provides a transport user supporting the Transport Interface (TI) with an alternate interface to a transport protocol provider supporting TI. This alternate interface allows the transport user to communicate with the transport protocol provider using the read() and write() functions.
tty(7) tty(7) NAME tty - controlling terminal interface DESCRIPTION The file /dev/tty is, in each process, a synonym for the control terminal associated with the process group of that process, if any. It is useful for programs or shell sequences that need to be sure of writing messages on the terminal no matter how output has been redirected.
UDP(7P) UDP(7P) NAME UDP - Internet User Datagram Protocol SYNOPSIS #include #include #include s = socket(AF_INET, SOCK_DGRAM, 0); s = socket(AF_INET6, SOCK_DGRAM, 0); DESCRIPTION UDP is a simple, unreliable datagram protocol used to support the SOCK_DGRAM socket type for the internet protocol family. UDP sockets are connectionless, and are normally used with the sendto() and recvfrom() calls (see send (2) and recv (2).
UNIX(7P) UNIX(7P) NAME UNIX - local communication domain protocol SYNOPSIS #include #include DESCRIPTION The local communication domain protocol, commonly referred to in the industry as the Unix domain protocol, utilizes the path name address format and the AF_UNIX address family. This protocol can be used as an alternative to the Internet protocol family (TCP/IP or UDP/IP) for communication between processes executing on the same node.
vxfsio(7) vxfsio(7) NAME vxfsio - VxFS file system control functions SYNOPSIS #include #include int ioctl(int fildes, int cmd, ... /∗ arg ∗/); DESCRIPTION The vxfs ioctl (2) enhancements provide for extended control over open files. The argument fildes is an open file descriptor. The data type and value of arg are specific to the type of command specified by cmd. Unless specified, arg is treated as an int type.
vxfsio(7) vxfsio(7) size_t dev_t vi_align_offset; vi_block_device; /* adj for alignment calculations */ /* bdev number for this cdev */ An application that tries to do efficient direct I/O or discovered direct I/O should issue read requests that are equal to the product of vi_read_nstream multiplied by vi_read_preferred_io. Generally any multiple or factor of vi_read_nstream multiplied by vi_read_preferred_io should be a good size for performance.
vxfsio(7) vxfsio(7) VX_FSO_DELAYLOG Indicates that some system calls may return before the intent log is written. (See the delaylog mount option of mount_vxfs (1M)). VX_FSO_NODATAINLOG Indicates that intent logging of user data for synchronous writes is disabled. (See the nodatainlog mount option of mount_vxfs (1M)). VX_FSO_NOLOG Indicates that intent logging of structural changes to the file system is disabled. (See the nolog mount option of mount_vxfs (1M)).
vxfsio(7) vxfsio(7) If an I/O request fails to meet alignment criteria, the I/O request is performed as a data synchronous I/O operation. VX_DSYNC Indicates that data synchronous I/O mode is desired. In data synchronous I/O mode, a write operation returns to the caller after the data has been transferred to external media, but the inode is not updated synchronously if only the times in the inode need to be updated.
vxfsio(7) vxfsio(7) The reservation amount is independent of file size since reservation is used to preallocate space for a file. The a_flags element is used to indicate the type of reservation required. The choices are: VX_ALIGN Align all new extents on an ext_size boundary relative to the starting block of an allocation unit. If VX_CONTIGUOUS is also set, the single extent allocated during this invocation is not subject to the alignment restriction.
vxfsio(7) vxfsio(7) EXAMPLES The following example shows how application code can use VX_GETFSOPT to find out if a JFS file system was mounted with the -o delaylog option: int arg = 0; int fd; ioctl(fd, VX_GETFSOPT, &arg); if (arg & VX_FSO_DELAYLOG) { printf("FS mounted with delaylog option!\n"); } DIAGNOSTICS Operation failures can return any of the following values in errno: EACCESS The calling process does not have write access to the file specified by fildes.
xopen_networking(7) xopen_networking(7) NAME xopen_networking - X/Open Networking Interfaces DESCRIPTION X/Open has defined XTI, Sockets, and IP Address Resolution interfaces in X/Open CAE Specification, Networking Services, Issue 4 (UNIX 95) and X/Open CAE Specification, Networking Services, Issue 5 (UNIX 98). For a detailed description of these interfaces, please refer to the above specifications or to the book Go Solo , which is published by Prentice Hall.
zero(7) zero(7) NAME zero - zero file DESCRIPTION /dev/zero is a zero special file. Reads from a zero special file always return characters whose value is ’0’ (\0 characters). Data written on a zero special file is discarded or ignored. Seeks on a zero special file will always succeed. Private mmap() of a zero special file is allowed (see mmap(2)). Shared mmap() is not allowed. EXAMPLES In the following example, the buffer ‘buf’ is filled with ‘len’ \0 characters. fildes = open("/dev/zero",...

glossary(9) glossary(9) In a text editor (such as vi, ex, ed, or sed), an address locates the line in a file on which a given instruction is intended. For adb, the address specifies at what assembly-language instruction to execute a given command. In disk utilities such as fsdb, address might refer to a raw or block special file, the inode number, volume header, or other file attribute.
glossary(9) glossary(9) computer’s hardware, find all devices accessible through the computer, and then load either a specified operating system or the first operating system found according to a specific search algorithm. A bA bus address A number which makes up part of the address HP-UX uses to locate a particular device. The bus address is determined by a switch setting on a peripheral device which allows the computer to distinguish between two devices connected to the same interface.
glossary(9) glossary(9) Command Set 1980 See CS/80. composite graphic symbol A graphic symbol consisting of a combination of two or more other graphic symbols in a single character position, such as a diacritical mark and a basic letter. control character A character other than a graphic character that affects the recording, processing, transmission, or interpretation of text. In the ASCII character set, control characters are those in the range 0 through 31, and 127.
glossary(9) glossary(9) defunct process See zombie process. A dA delta A term used in the Source Code Control System (SCCS) to describe a unit of one or more textual changes to an SCCS file. Each time an SCCS file is edited, changes made to the file are stored separately as a delta. The get (1) command is then used to specify which deltas are to be applied to or excluded from the SCCS file, thus yielding a particular version of the file.
glossary(9) glossary(9) process appear to be the file’s owner, enabling the process to access files which must be accessed in order for the program to execute successfully. (Many HP-UX commands which are owned by root, such as mkdir and mail, have their set-user-ID bit set so other users can execute these commands.) If the file’s set-user-ID bit is not set, the process’s effective user ID is inherited from that process’s parent. See real user ID and set-user-ID bit.
glossary(9) glossary(9) Read, write, and execute/search permissions on a file are granted to a process if any of the following conditions are met: • The process’s effective user ID is superuser. • The process’s effective user ID matches the user ID of the owner of the file and the appropriate access bit of the owner portion (0700) of the file mode is set.
glossary(9) file pointer glossary(9) A data element obtained through any of the fopen (3S) standard I/O library routines that ‘‘points to’’ (refers to) a file opened for reading and/or writing, and which keeps track of where the next I/O operation will take place in the file (in the form of a byte offset relative to the beginning of the file). After obtaining the file pointer, it must thereafter be used to refer to the open file when using any of the standard I/O library routines.
glossary(9) glossary(9) your group in the file’s mode, you can access the file. When the identity of a group is associated with a process, a group ID value is referred to as a real group ID, an effective group ID, a supplementary group ID, or a saved group ID. See also privileged group and set-group-ID bit. group access list A set of supplementary group IDs used in determining resource accessibility. Access checks are performed as described in file access permissions.
glossary(9) intrinsic glossary(9) See system call. I/O redirection A mechanism provided by the HP-UX shell for changing the source of data for standard input and/or the destination of data for standard output and standard error. See sh(1). ITE See Internal Terminal Emulator. job control Job control allows users to selectively stop (suspend) execution of processes and continue (resume) their execution at a later time.
glossary(9) glossary(9) Logical Interchange Format (LIF) A standard format for mass storage implemented on many Hewlett-Packard computers to aid in media transportability. See lif (4) for more detail. login The process of gaining access to HP-UX. This consists of successful execution of the login sequence defined by login (1), which varies depending on the system configuration. It requests a login name and possibly one or more passwords.
glossary(9) glossary(9) operation is indicated for each operation. Whether a particular process has these permissions for an object is determined by the object’s permission mode bits as follows: 00400 00200 00060 00006 Read by user Write by user Read, Write by group Read, Write by others Read and Write permissions on a msqid are granted to a process if one or more of the following are true: • The process’s effective user ID is superuser. • The process’s effective user ID matches msg_perm.
glossary(9) glossary(9) /etc/inittab. Do not confuse the multiuser system with the multiuser state. A multiuser system is a system which can have more than one user actively communicating with the system when it is in the multiuser state. The multiuser state removes the single-user restriction imposed by the single-user state (see single-user state, inittab (4)).
glossary(9) glossary(9) parent process Whenever a new process is created by a currently-existing process (via fork (2)), the currently existing process is said to be the parent process of the newly created process. Every process has exactly one parent process (except the init process, see init), but each process can create several new processes with the fork (2) system call. The parent process ID of any process is the process ID of its creator.
glossary(9) glossary(9) pipe An interprocess I/O channel used to pass data between two processes. It is commonly used by the shell to transfer data from the standard output of one process to the standard input of another. On a command line, a pipe is signaled by a vertical bar (|). Output from the command to the left of the vertical bar is channeled directly into the standard input of the command on the right.
glossary(9) glossary(9) control and address space exist until it terminates. It then enters an inactive state where certain resources may be returned to the system, although some resources, such as the process ID are still in use. When another process executes a wait(), wait3(), or waitpid() function (see wait (2)) for an inactive process, the remaining resources are returned to the system. The last resource to be returned to the system is the process ID. At this time, the lifetime of the process ends.
glossary(9) glossary(9) relative path name A path name that does not begin with a slash (/). It indicates that a file’s location is given relative to your current working directory, and that the search begins there (instead of at the root directory). For example, dir1/file2 searches for the directory dir1 in your current working directory; then dir1 is searched for the file file2. root directory (1) The highest level directory of the hierarchical file system, from which all other files branch.
glossary(9) glossary(9) the shell variable PS2 appropriately in your .profile file. (The C shell has no secondary prompt.) select code On Series 700 systems, part of an address used for devices. Multiple peripherals connected to the same interface card share the same select code. On Series 700 systems, select code consists of the bus and slot numbers for a device, both of which are determined by the particular I/O slot in which the I/O card resides.
glossary(9) glossary(9) • The process’s effective user ID does not match sem_perm.[c]uid and the appropriate bit of the ‘‘group’’ portion (060) of sem_perm.mode is set. • The process’s effective user ID does not match sem_perm.[c]uid and the process’s effective group ID does not match sem_perm.[c]gid and neither of sem_perm.[c]gid is in the process’s group access list and the appropriate bit of the ‘‘other’’ portion (06) of sem_perm.mode is set. Otherwise, the corresponding permissions are denied.
glossary(9) glossary(9) shm_segsz specifies the size of the shared memory segment. shm_cpid is the process id of the process that created the shared memory identifier. shm_lpid is the process id of the last process that performed a shmop (2) operation. shm_nattch is the number of processes that currently have this segment attached.
glossary(9) glossary(9) solidus See slash. source code The fundamental high-level information (program) written in the syntax of a specified computer language. Object (machine-language) code is derived from source code. When dealing with an HP-UX shell command language, source code is input to the command language interpreter. The term shell script is synonymous with this meaning. When dealing with the C Language, source code is input to the cc(1) command.
glossary(9) glossary(9) Subset 1980 See CS/80. superblock A block on each file system’s mass storage medium which describes the file system. The contents of the superblock vary between implementations. Refer to the system administrator manuals supplied with your system for details. superuser The HP-UX system administrator. This user has access to all files, and can perform privileged operations. superuser has a real user ID and effective user ID of 0, and, by convention, the user name of root.
glossary(9) glossary(9) becomes a process group leader via the setpgrp (2) system call, its terminal affiliation is broken. See process group, process group leader, terminal group, and setpgrp (2). terminal device See terminal. text file A file that contains characters organized into one or more lines. The lines cannot contain NUL characters, and none can exceed LINE_MAX bytes in length including the terminating newline character.
introduction(9) introduction(9) NAME introduction - introduction to the HP-UX operating system and the HP-UX Reference INTRODUCTION HP-UX is the Hewlett-Packard Company’s implementation of an operating system that is compatible with various industry standards. It is based on the UNIX System V Release 4 operating system and includes important features from the Fourth Berkeley Software Distribution.
introduction(9) introduction(9) Section 1: User Commands Programs that are usually invoked directly by users or from command language procedures (scripts). Section 1M: System Administration Commands Commands used for system installation and maintenance, including boot processes, crash recovery, system integrity testing, and other needs. Most commands in this section require the superuser privilege. A A Section 2: System Calls Entries into the HP-UX kernel, including the C-language interface.
introduction(9) introduction(9) it is unwise to have files names that begin with -, +, or =. DESCRIPTION Discusses the function and behavior of each entry. EXTERNAL INFLUENCES Information under this heading pertains to programming for various spoken languages. Typical entries indicate support for single- or multibyte characters, the effect of language-related environment variables on system behavior, and other related information.
introduction(9) introduction(9) XPG3 X/Open Portability Guide Issue 3 (X/Open, Ltd.) XPG4 X/Open Portability Guide Issue 4 (X/Open, Ltd.) XPG4.2 X/Open Portability Guide Issue 4 (X/Open, Ltd.) Version 2 GETTING STARTED WITH HP-UX This is a very brief overview of how to use the HP-UX system: how to log in and log out, how to communicate through your machine, and how to run a program. A A HP-UX uses control characters to perform certain functions.
introduction(9) intr quit ^? (DEL; Delete, Rub, Rubout) ^\ (FS) start stop ˆQ (DC1; X-ON) ^S (DC3; X-OFF) introduction(9) ^C (ETX) The eof character terminates "file" input from the terminal, as read by programs and scripts. By extension, eof can also terminate the shell (see the Logging Out subsection above). The kill character deletes all characters typed before it on a terminal input line. The erase character erases the last character typed.
introduction(9) introduction(9) or working directory, and any file name you type is assumed to be in that directory by default. Because you are the owner of this directory, you have full permission to read, write, alter, or destroy its contents. The permissions you have for other directories and files will have been granted or denied to you by their respective owners, or by the system administrator. To change the current working directory use cd(1).
