NAME
getsockname - get socket name
SYNOPSIS
#include <sys/socket.h>
int getsockname(int s, struct sockaddr *name, socklen_t *namelen);
DESCRIPTION
Getsockname
returns the current
name
for the specified socket. The
namelen
parameter should be initialized to indicate
the amount of space pointed to by
name.
On return it contains the actual size of the name
returned (in bytes).
RETURN VALUE
On success, zero is returned. On error, -1 is returned, and
errno
is set appropriately.
ERRORS
- EBADF
-
The argument
s
is not a valid descriptor.
- EFAULT
-
The
name
parameter points to memory not in a valid part of the
process address space.
- ENOBUFS
-
Insufficient resources were available in the system
to perform the operation.
- ENOTSOCK
-
The argument
s
is a file, not a socket.
CONFORMING TO
SVr4, 4.4BSD (the
getsockname
function call appeared in 4.2BSD). SVr4 documents additional ENOMEM
and ENOSR error codes.
NOTE
The third argument of
getsockname
is in reality an `int *' (and this is what BSD 4.* and libc4 and libc5 have).
Some POSIX confusion resulted in the present socklen_t, also used by glibc.
