                                                                                    explain_socketpair_or_die(3)

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

       The  explain_socketpair_on_error  function  is  used to call the socketpair(2) system call. On failure an
       explanation will be printed to stderr,  obtained  from  the  explain_socketpair(3)  function,  but  still
       returns to the caller.

       domain  The domain, exactly as to be passed to the socketpair(2) system call.

       type    The type, exactly as to be passed to the socketpair(2) system call.

       protocol
               The protocol, exactly as to be passed to the socketpair(2) system call.

       sv      The sv, exactly as to be passed to the socketpair(2) system call.

       The  explain_socketpair_or_die  function  is  intended  to  be used in a fashion similar to the following
       example:
              explain_socketpair_or_die(domain, type, protocol, sv);

       explain_socketpair_or_die - create pair of connected sockets and report errors

       The  explain_socketpair_or_die  function only returns on success, see socketpair(2) for more information.
       On failure, prints an explanation and exits, it does not return.

       The explain_socketpair_on_error function always returns the value return  by  the  wrapped  socketpair(2)
       system call.

socketpair(2)
               create a pair of connected sockets

       explain_socketpair(3)
               explain socketpair(2) errors

       exit(2) terminate the calling process
