GETSOCKNAME(2)		   Linux Programmer's Manual		GETSOCKNAME(2)

NAME
       getsockname - get socket name

SYNOPSIS
       #include <sys/socket.h>

       int getsockname(int sockfd, struct sockaddr *addr, socklen_t *addrlen);

DESCRIPTION
       getsockname() returns the current address to which the socket sockfd is
       bound, in the buffer pointed to by addr.	 The addrlen  argument	should
       be initialized to indicate the amount of space (in bytes) pointed to by
       addr.  On return it contains the actual size of the socket address.

       The returned address is truncated if the buffer provided is too	small;
       in  this case, addrlen will return a value greater than was supplied to
       the call.

RETURN VALUE
       On success, zero is returned.  On error, -1 is returned, and  errno  is
       set appropriately.

ERRORS
       EBADF  The argument sockfd is not a valid descriptor.

       EFAULT The  addr	 argument  points to memory not in a valid part of the
	      process address space.

       EINVAL addrlen is invalid (e.g., is negative).

       ENOBUFS
	      Insufficient resources were available in the system  to  perform
	      the operation.

       ENOTSOCK
	      The argument sockfd is a file, not a socket.

CONFORMING TO
       SVr4,  4.4BSD  (the  getsockname()  function  call appeared in 4.2BSD),
       POSIX.1-2001.

NOTES
       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).
