- * pthread_delay_np
- *
- * DESCRIPTION
- *
- *       This routine 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. 
- *
- *       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 cancelation request. 
- *
- *       The timespec structure contains the following two fields: 
- *
- *            tv_sec is an integer number of seconds. 
- *            tv_nsec is an integer 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: 
- *
- *  0 
- *           Successful completion.
- *  [EINVAL] 
- *           The value specified by interval is invalid. 
- *
- * Example
- *
- * The following code segment would wait for 5 and 1/2 seconds
- *
- *  struct timespec tsWait;
- *  int      intRC;
- *
- *  tsWait.tv_sec  = 5;
- *  tsWait.tv_nsec = 500000000L;
- *  intRC = pthread_delay_np(&tsWait);
