const struct timespec *delta,
struct timespec *abstime);

If threads are not present, this routine has no effect. to sleep(3).
This routine adds a specified time interval to the current absolute system time and returns a new absolute time. This new absolute time is
used as the expiration time in a call to tis_cond_timedwait(3).
The timespec structure contains the following two fields: tv_sec is an integral number of seconds. tv_nsec is an integral number of
nanoseconds.
RETURN VALUES
If an error condition occurs, this routine returns an integer value indicating the type of error. Possible return values are as follows:
