<h4><a name="tag_03_777_03"></a>DESCRIPTION</h4>
|
|
|
|
<blockquote>
|
|
<p>The <i>timer_delete</i>() function deletes the specified timer, <i>timerid</i>, previously created by the <a href=
|
|
"../functions/timer_create.html"><i>timer_create</i>()</a> function. If the timer is armed when <i>timer_delete</i>() is called,
|
|
the behavior shall be as if the timer is automatically disarmed before removal. The disposition of pending signals for the deleted
|
|
timer is unspecified.</p>
|
|
</blockquote>

|
|
|
<h4><a name="tag_03_777_04"></a>RETURN VALUE</h4>
