GETSOCKNAME(3P)		   POSIX Programmer's Manual	       GETSOCKNAME(3P)

PROLOG
       This  manual  page is part of the POSIX Programmer's Manual.  The Linux
       implementation of this interface may differ (consult the	 corresponding
       Linux  manual page for details of Linux behavior), or the interface may
       not be implemented on Linux.

NAME
       getsockname - get the socket name

SYNOPSIS
       #include <sys/socket.h>

       int getsockname(int socket, struct sockaddr *restrict address,
	      socklen_t *restrict address_len);

DESCRIPTION
       The getsockname() function shall retrieve the locally-bound name of the
       specified  socket, store this address in the sockaddr structure pointed
       to by the address argument, and store the length of this address in the
       object pointed to by the address_len argument.

       If  the	actual length of the address is greater than the length of the
       supplied sockaddr structure, the stored address shall be truncated.

       If the socket has not been bound to a local name, the value  stored  in
       the object pointed to by address is unspecified.

RETURN VALUE
       Upon  successful	 completion, 0 shall be returned, the address argument
       shall point to the address of the socket, and the address_len  argument
       shall  point  to	 the  length  of  the address.	Otherwise, -1 shall be
       returned and errno set to indicate the error.

ERRORS
       The getsockname() function shall fail if:

       EBADF  The socket argument is not a valid file descriptor.

       ENOTSOCK
	      The socket argument does not refer to a socket.

       EOPNOTSUPP
	      The operation is not supported for this socket's protocol.

       The getsockname() function may fail if:

       EINVAL The socket has been shut down.

       ENOBUFS
	      Insufficient resources were available in the system to  complete
	      the function.
