HP-UX Reference (11i v3 07/02) - 2 System Calls (vol 5)

e
errno(2) errno(2)
[ECONNREFUSED]
Connection refused. No connection could be made because the target machine actively
refused it. This usually results from trying to connect to a service that is inactive on the
foreign host.
[ECONNRESET]
Connection reset by peer. A connection was forcibly closed by a peer. This normally results
from the peer executing a shutdown() call (see shutdown(2)).
[EDEADLK] Resource deadlock would occur. A process which has locked a system resource would have
been put to sleep while attempting to access another process’ locked resource.
[EDESTADDRREQ]
Destination address required. A required address was omitted from an operation on a
socket.
[EDOM] Math argument. The argument of a function in the math package (3M) is out of the domain
of the function.
[EEXIST] File exists. An existing file was mentioned in an inappropriate context; e.g.,
link().
[EFAULT] Bad address. The system encountered a hardware fault in attempting to use an argument
of a system call; can also result from passing the wrong number of parameters to a system
call. The reliable detection of this error is implementation dependent.
[EFBIG] File too large. The size of a file exceeded the maximum file size (for the file system) or
ULIMIT was exceeded (see ulimit(2)), or a bad semaphore number in a semop() call (see
semop(2)).
[EHOSTDOWN]
Host is down. A socket operation encountered a dead host. Networking activity on the
local host has not been initiated.
[EHOSTUNREACH]
No route to host. A socket operation was attempted to an unreachable host.
[EIDRM] Identifier Removed. This error is returned to processes that resume execution due to the
removal of an identifier from the file system’s name space (see msgctl(2), semctl(2), and
shmctl(2)).
[EILSEQ] Illegal byte sequence. A wide character code has been detected that does not correspond to
a valid character, or a byte sequence does not form a valid wide character code.
[EINPROGRESS]
Operation now in progress. An operation that takes a long time to complete was attempted
on a nonblocking object (see ioctl(2) and fcntl(2)).
[EINTR] Interrupted system call. An asynchronous signal (such as interrupt or quit), which the user
has elected to catch, occurred during a system call. If execution is resumed after process-
ing the signal, it will appear as if the interrupted system call returned this error condition
unless the system call is restarted (see signal(5)).
[EINVAL] Invalid argument. Some invalid argument (such as unmounting a device that is not
currently mounted, mentioning an undefined signal in
signal() or kill(),orreading
or writing a file for which lseek() has generated a negative pointer). Also set by the
math functions described in the (3M) entries of this manual.
[EIO] I/O error − some physical I/O error. This error may in some cases occur on a call following
the one to which it actually applies.
[EISCONN] Socket is already connected. A connect() request was made on an already connected
socket, or, a sendto() or sendmsg() request on a connected socket specified a destina-
tion other than the connected party.
[EISDIR] Is a directory. An attempt to open a directory for writing.
[ELOOP] Too many levels of symbolic links were encountered while resolving a path name. See
fs_symlinks(5) for more information.
[EMFILE] Too many open files. No process may have more than a system-defined number of file
descriptors open at a time.
