Calling the function with this flag set to <CODE>true</CODE> clears the &quot;execution complete&quot; status. Tasks whose execution counts are non-zero are rescheduled immediately after the previous task execution completes. This causes the return value to switch to <CODE>TASK_WAITING_TIMER</CODE> the next time the function is called. (Optional)</td>

49<h2>Description</h2>
50    <div class="section">
51<p>Gets the task state. 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> (wait for time after calling <CODE>Start</CODE>)<br />(3) <CODE>TASK_WAITING</CODE> (waiting for execution)<br />(4) <CODE>TASK_RUNNING</CODE> or <CODE>TASK_RETRY</CODE> (task running)<br />(5) <CODE>TASK_DONE</CODE> or <CODE>TASK_ERROR</CODE> (task 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>
