explain_time_or_die(3)					     Library Functions Manual					    explain_time_or_die(3)

NAME

       explain_time_or_die - get time in seconds and report errors

SYNOPSIS

       #include <libexplain/time.h>
       time_t explain_time_or_die(time_t *t);
       time_t explain_time_on_error(time_t *t);

DESCRIPTION

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

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

       t       The t, exactly as to be passed to the time(2) system call.

RETURN VALUE

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

       The explain_time_on_error function always returns the value return by the wrapped time(2) system call.

EXAMPLE

       The explain_time_or_die function is intended to be used in a fashion similar to the following example:
	      time_t result = explain_time_or_die(t);

SEE ALSO

       time(2) get time in seconds

       explain_time(3)
	       explain time(2) errors

       exit(2) terminate the calling process

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);

SEE ALSO

       socketpair(2)
	       create a pair of connected sockets

       explain_socketpair(3)
	       explain socketpair(2) errors

       exit(2) terminate the calling process
