explain_settimeofday_or_die3
Sets system time and report errors
Usage
#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);
Overview
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.
Examples
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);Releases
