GETSOCKNAME(2)		   Linux Programmers Manual	       GETSOCKNAME(2)



NAME
       getsockname - get socket name

SYNOPSIS
       #include 

       int getsockname(int s, struct sockaddr *name, socklen_t *namelen);

DESCRIPTION
       getsockname()  returns  the current name for the specified socket.  The
       namelen argument 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  argument  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.

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).
