NAME

       explain_socketpair_or_die - create pair of connected sockets and report errors

SYNOPSIS

       #include <libexplain/socketpair.h>
       void explain_socketpair_or_die(int domain, int type, int protocol, int *sv);
       int explain_socketpair_on_error(int domain, int type, int protocol, int *sv);

DESCRIPTION

       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.

RETURN VALUE

       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.

EXAMPLE

       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);
