NAME

explain_settimeofday_or_die - sets system time and report errors

SYNOPSIS

#include <libexplain/settimeofday.h>

void explain_settimeofday_or_die(const struct timeval *tv, const struct timezone *tz);
int explain_settimeofday_on_error(const struct timeval *tv, const struct timezone *tz);

DESCRIPTION

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

The explain_settimeofday_on_error function is used to call the settimeofday(2) system call. On failure an explanation will be printed to stderr, obtained from the explain_settimeofday(3) function, but still returns to the caller.

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

RETURN VALUE

The explain_settimeofday_or_die function only returns on success, see settimeofday(2) for more information. On failure, prints an explanation and exits, it does not return.

The explain_settimeofday_on_error function always returns the value return by the wrapped settimeofday(2) system call.

EXAMPLE

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

explain_settimeofday_or_die(tv, tz);
