Calling the function with this flag set to <CODE>true</CODE> clears the "execution complete" status. Tasks whose execution counts are non-zero are rescheduled immediately after the previous task execution completes.

In most cases, tasks transition from step 1 through 5 below. <br />(1) <CODE>TASK_REGISTERED</CODE> (task registered)<br />(2) <CODE>TASK_WAITING_TIMER</CODE> (waiting for time after <CODE>Start</CODE> function is called)<br />(3) <CODE>TASK_WAITING</CODE> (waiting for execution)<br />(4) <CODE>TASK_RUNNING</CODE> or <CODE>TASK_RETRY</CODE> (task is running)<br />(5) <CODE>TASK_DONE</CODE> or <CODE>TASK_ERROR</CODE> (task is complete)<br /><br />There are also two special states, <CODE>TASK_PAUSED</CODE> (paused) and <CODE>TASK_STOPPED</CODE> (stopped due to a call to <CODE>Cancel</CODE>). State transitions may occur in a short period of time. Accordingly, the function may not always return all states. </p><!-- write here --></div> 52<h2>Revision History</h2> 53 <div class="section"> 54 <dl class="history"> 55 <dt>2010/09/16</dt> 56<dd>Initial version.<br /> 57 </dd> 58 </dl> 59 </div> 60 <hr><p>CONFIDENTIAL</p></body> 61</html> 62
