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).

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  parameter points to memory not in a valid part of the
              process address space.

       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).
       SVr4 documents additional ENOMEM and ENOSR error codes.

NOTE

       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).
