explain_gettimeofday_or_die3

Usage

Overview

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.
