NAME
       explain_getsockname_or_die - get socket name and report errors

SYNOPSIS
       #include <libexplain/getsockname.h>
       void explain_getsockname_or_die(int fildes, struct sockaddr *sock_addr, socklen_t *sock_addr_size);

DESCRIPTION
       The  explain_getsockname_or_die	function  is  used  to	call the getsockname(2) system call.  On failure an explanation will be printed to
       stderr, obtained from explain_getsockname(3), and then the process terminates by calling exit(EXIT_FAILURE).

       This function is intended to be used in a fashion similar to the following example:
	      struct sockaddr sock_addr;
	      socklen_t sock_addr_size = sizeof(sock_addr);
	      explain_getsockname_or_die(fildes, &sock_addr, &sock_addr_size);

       fildes  The fildes, exactly as to be passed to the getsockname(2) system call.

       sock_addr
	       The sock_addr, exactly as to be passed to the getsockname(2) system call.

       sock_addr_size
	       The sock_addr_size, exactly as to be passed to the getsockname(2) system call.

       Returns:
	       This function only returns on success, see getsockaddr(1) for more information.	On failure, prints an explanation and exits.
