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).
        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  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.
        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).
