NAME

explain_gettimeofday_or_die - get time and report errors

SYNOPSIS

#include <libexplain/gettimeofday.h>
void explain_gettimeofday_or_die(struct timeval *tv, struct timezone *tz);

DESCRIPTION

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

This function is intended to be used in a fashion similar to the following example:

explain_gettimeofday_or_die(tv, tz);

	tv		The tv, exactly as to be passed to the gettimeofday(2) system call.
	tz		The tz, exactly as to be passed to the gettimeofday(2) system call.

Returns:

This function only returns on success. On failure, prints an explanation and exits.
