                                                                                   explain_getsockname_or_die(3)

       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.
