- * Provide pthread_delay_np posix function for NT
- *
- * 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);
