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);
