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

TagDescription
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.
EINVAL namelen is invalid (e.g., is negative).
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), POSIX.1-2001.

NOTE

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).
