SYNOPSIS
       #include <network.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.  A 0 is returned if the
       call succeeds, -1 if it fails.

ERRORS

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

       ENOBUFS Insufficient resources were available in the  sys-
               tem to perform the operation.
