| <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> | |
