34<td>Once a task finishes running, this stores the &quot;task is complete&quot; state so that the task's execution results can be checked. Calling the function with this flag set to <CODE>true</CODE> clears the &quot;complete&quot; state. 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.</p><p>In most cases, task states transition from state 1 through state 5 below.<br /><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 by a call to <CODE>Cancel</CODE>).<br /><br /><B>Note:</B> Because state transitions sometimes occur in a short period of time, the function may not always be able to get all states.</p><!-- write here --></div>
