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



NAME
       getsockname - get socket(2,7,n) 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(1,8) bytes).

RETURN VALUE
       On success, zero is returned.  On error(8,n), -1 is returned, and  errno  is
       set(7,n,1 builtins) appropriately.

ERRORS
       EBADF  The argument s is not a valid descriptor.

       EFAULT The  name  parameter points to memory not in(1,8) a valid part of the
              process address space.

       ENOBUFS
              Insufficient resources were available in(1,8) the system  to  perform
              the operation.

       ENOTSOCK
              The argument s is a file(1,n), not a socket.

CONFORMING TO
       SVr4,  4.4BSD (the getsockname function call appeared in(1,8) 4.2BSD).  SVr4
       documents additional ENOMEM and ENOSR error(8,n) codes.

NOTE
       The third argument of getsockname is in(1,8) reality an `int *' (and this is
       what  BSD 4.* and libc4 and libc5 have).  Some POSIX confusion resulted
       in(1,8) the present socklen_t, also used by glibc.  See also accept(2,8)(2).
