SYNOPSIS #include <libexplain/sleep.h> unsigned int explain_sleep_or_die(unsigned int seconds); unsigned int explain_sleep_on_error(unsigned int seconds);
DESCRIPTION The explain_sleep_or_die function is used to call the sleep(3) system call. On failure an explanation will be printed to stderr, obtained from the explain_sleep(3) function, and then the process terminates by calling exit(EXIT_FAILURE). The explain_sleep_on_error function is used to call the sleep(3) system call. On failure an explanation will be printed to stderr, obtained from the explain_sleep(3) function, but still returns to the caller. seconds The seconds, exactly as to be passed to the sleep(3) system call.
RETURN VALUE The explain_sleep_or_die function only returns on success, see sleep(3) for more informa‐ tion. On failure, prints an explanation and exits, it does not return. The explain_sleep_on_error function always returns the value return by the wrapped sleep(3) system call.
