Function Documentation

void explain_gettimeofday_or_die	(	struct timeval *	tv,
		struct timezone *	tz
	)

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 the explain_gettimeofday(3) function, 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);

Parameters:

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, it does not return.
