getsockname

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



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.

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

       ENOBUFS
	      Insufficient  resources were available in the system to perform
	      the operation.

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

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	 BSD  4.*  and	libc4  and libc5 have).	 Some POSIX confusion
       resulted in the present socklen_t.  The draft standard  has  not	 been
       adopted yet, but glibc2 already follows it and also has socklen_t. See
       also accept(2).
