explain_gettimeofday_or_die - get time and report errors

#include <libexplain/gettimeofday.h>

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 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);
The tv, exactly as to be passed to the gettimeofday(2) system call.
The tz, exactly as to be passed to the gettimeofday(2) system call.
This function only returns on success. On failure, prints an explanation and exits.

gettimeofday(2)
get time
explain_gettimeofday(3)
explain gettimeofday(2) errors
exit(2)
terminate the calling process
