<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>
