<H2><A HREF="#toc2" NAME="sect2">Description</A></H2>
<P><B>pthread_delay_np</B> causes a thread to delay execution for a
specific period of time. This period ends at the current time plus
the specified interval. The routine will not return before the end of
the period is reached, but may return an arbitrary amount of time
after the period has gone by. This can be due to system load, thread
priorities, and system timer granularity.</P>
<P>Specifying an interval of zero (0) seconds and zero (0)
nanoseconds is allowed and can be used to force the thread to give up
the processor or to deliver a pending cancellation request.</P>
