explain_stime_or_die(3) 				     Library Functions Manual					   explain_stime_or_die(3)

NAME
explain_stime_or_die - set system time and report errors SYNOPSIS
#include <libexplain/stime.h> void explain_stime_or_die(time_t *t); int explain_stime_on_error(time_t *t); DESCRIPTION
The explain_stime_or_die function is used to call the stime(2) system call. On failure an explanation will be printed to stderr, obtained from the explain_stime(3) function, and then the process terminates by calling exit(EXIT_FAILURE). The explain_stime_on_error function is used to call the stime(2) system call. On failure an explanation will be printed to stderr, obtained from the explain_stime(3) function, but still returns to the caller. t The t, exactly as to be passed to the stime(2) system call. RETURN VALUE
The explain_stime_or_die function only returns on success, see stime(2) for more information. On failure, prints an explanation and exits, it does not return. The explain_stime_on_error function always returns the value return by the wrapped stime(2) system call. EXAMPLE
The explain_stime_or_die function is intended to be used in a fashion similar to the following example: explain_stime_or_die(t); SEE ALSO
stime(2) set system time explain_stime(3) explain stime(2) errors exit(2) terminate the calling process COPYRIGHT
