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);
