<p>Intel® Threading Building Blocks (Intel® TBB) 2.2 and later automatically initializes the
task scheduler. You can use class
<samp class="codeph">task_scheduler_init</samp> to explicitly initialize the task
scheduler, which can be useful for doing any of the following:
</p>
<ul type="disc">
<li>
<p>Control when the task scheduler is constructed and destroyed.
</p>
</li>
<li>
<p>Specify the number of threads used by the task scheduler.
</p>
</li>
<li>
<p>Specify the stack size for worker threads.
</p>
</li>
</ul>
