getsockname(2) |
 |
getsockname − get socket name
#include <sys/socket.h>
int getsockname(int s, struct sockaddr *name, socklen_t *namelen);
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).
On success, zero is returned. On error, −1 is returned, and errno is set appropriately.

ENOBUFS

ENOTSOCK
The argument s is a file, not a socket.
SVr4, 4.4BSD (the getsockname() function call appeared in 4.2BSD), POSIX.1-2001.
The third argument of getsockname() is in reality an ’int *’ (and this is what 4.x BSD and libc4 and libc5 have). Some POSIX confusion resulted in the present socklen_t, also used by glibc. See also accept(2).
