<a name="1204795"> </a><font size=2 face="Verdana, Arial, Helvetica, sans-serif">Sometimes, a task needs to voluntarily give up control of the CPU so that another task at the same priority can execute, that is, terminate the current timeslice. This may be achieved with the function:</font>
</p>
<a name="1204797"> </a><font size=2 face=Courier><strong>void task_reschedule (void);<br></strong></font>
<p>
<a name="1204798"> </a><font size=2 face="Verdana, Arial, Helvetica, sans-serif">This provides a clean way of suspending execution of a task in favor of the next task on the scheduling list, but without losing priority. The task which executes <font size=2 face=Courier><strong>task_reschedule</strong></font> is added to the back of the scheduling list and the task at the front of the scheduling list is promoted to be the new current task.</font>
</p>
<p>
<a name="1204799"> </a><font size=2 face="Verdana, Arial, Helvetica, sans-serif">A task may be inadvertently rescheduled when the <font size=2 face=Courier><strong>task_priority_set()</strong></font> function is used; see <a href="task4.htm#1204661"><font color="#0000ff" face="Verdana, Arial, Helvetica, sans-serif"><i>Section⌨️ 快捷键说明
