localization
The process of adapting existing software to meet the local language, customs, and character set require-
ments of a particular geographical area.
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 pos-
sibly one or more passwords.
login directory
The directory in which you are placed immediately after you log in. This directory is defined for each user
in the file
/etc/passwd . The shell variable
HOME is set automatically to your login directory by
login(1) immediately after you log in. See home directory.
magic number
The first word of an
a.out-format or archive file. This word contains the system ID, which states what
machine (hardware) the file will run on, and the file type (executable, sharable executable, archive, etc.).
major number
A number used exclusively to create special files that enable I/O to or from specific devices. This number
indicates which device driver to use for the device. Refer to mknod(2) and the System Administrator
manual supplied with your system for details.
message catalog
Program strings, such as program messages and prompts, are stored in a message catalog corresponding
to a particular geographical area. Retrieval of a string from a message catalog is based on the value of
the user’s
LANG environment variable (see LANG).
message queue identifier (msqid)
A unique positive integer created by a msgget(2) system call. Each msqid has a message queue and a data
structure associated with it. The data structure is referred to as msqid_ds and contains the following
members:
struct
ipc_perm msg_perm; /* operation permission */
ulong msg_qnum; /* number of msgs on q */
ulong msg_qbytes; /* max number of bytes on q */
ulong msg_cbytes; /* current number of bytes on q */
ushort msg_lspid; /* pid of last msgsnd operation */
ushort msg_lrpid; /* pid of last msgrcv operation */
time_t msg_stime; /* last msgsnd time */
time_t msg_rtime; /* last msgrcv time */
time_t msg_ctime; /* last change time */
/* Times measured in secs since */
/* 00:00:00 GMT, Jan. 1, 1970 */
Message queue identifiers can be created using ftok(3C).
msg_perm is a ipc_perm structure that specifies the message operation permission (see below). This
structure includes the following members:
ushort cuid; /* creator user id */
ushort cgid; /* creator group id */
ushort uid; /* user id */
ushort gid; /* group id */
ushort mode; /* r/w permission */
msg_qnum
is the number of messages currently on the queue. msg_qbytes is the maximum number of
bytes allowed on the queue. msg_lspid is the process id of the last process that performed a msgsnd
operation. msg_lrpid is the process id of the last process that performed a msgrcv operation.
msg_stime is the time of the last msgsnd operation, msg_rtime is the time of the last msgrcv
