NAME explain_nanosleep_or_die - high‐resolution sleep and report errors
SYNOPSIS #include <libexplain/nanosleep.h> void explain_nanosleep_or_die(const struct timespec *req, struct timespec *rem); int explain_nanosleep_on_error(const struct timespec *req, struct timespec *rem);
DESCRIPTION The explain_nanosleep_or_die function is used to call the nanosleep(2) system call. On failure an explanation will be printed to stderr, obtained from the explain_nanosleep(3) function, and then the process terminates by calling exit(EXIT_FAILURE). The explain_nanosleep_on_error function is used to call the nanosleep(2) system call. On failure an explanation will be printed to stderr, obtained from the explain_nanosleep(3) function, but still returns to the caller. req The req, exactly as to be passed to the nanosleep(2) system call. rem The rem, exactly as to be passed to the nanosleep(2) system call.
RETURN VALUE The explain_nanosleep_or_die function only returns on success, see nanosleep(2) for more information. On failure, prints an explanation and exits, it does not return. The explain_nanosleep_on_error function always returns the value return by the wrapped nanosleep(2) system call.
EXAMPLE The explain_nanosleep_or_die function is intended to be used in a fashion similar to the following example: explain_nanosleep_or_die(req, rem);
