<a name="289903">
</a><h4>Overview</h4>
Schedule a procedure to run at specified intervals
<a name="289904">
</a><a name="289905">
</a><h4>Syntax</h4>
<pre> <a name="289906"></a>int Ns_ScheduleProcEx(
<a name="289907"></a>Ns_SchedProc *proc,
<a name="289908"></a>void *context,
<a name="289909"></a>int flags,
<a name="289910"></a>int interval,
<a name="289911"></a>Ns_SchedProc *cleanup
<a name="289912"></a>);
</pre><p><a name="289914">
</a><h4>Description</h4>
<p><a name="289915">
</a>The Ns_ScheduleProcEx function schedules the procedure (<code>proc</code>) to be run at a specific time interval specified in seconds. Ns_ScheduleProcEx returns an integer id for use in the Ns_UnscheduleProc function.</p>
<p><a name="289916">
</a>The <code>proc</code> procedure is the scheduled procedure that will be run at each interval. It is a function that takes the context and id of the schedule procedure. The <code>id</code> can be used in the Ns_UnscheduleProc procedure to stop the procedure from being called again.</p>
<pre> <a name="289917"></a>typedef void (Ns_SchedProc) (void *context, int id);
</pre><p><p><a name="289918">
</a>The <code>context</code> is the context to pass to the scheduled procedure.</p>
<p><a name="289919">
</a>The possible flags are NS_SCHED_ONCE and NS_SCHED_THREAD. If you specify NS_SCHED_ONCE, the procedure will only be executed once on the specified day and time, and it will not be re-scheduled to execute again. By default, the procedure is re-scheduled after every time it is executed. </p>
<p><a name="289920">
</a>If you specify NS_SCHED_THREAD, the procedure will run detached in a separate thread instead of using the one scheduled procedure thread used by all other scheduled procedures. You should use NS_SCHED_THREAD if the procedure will not return immediately. Note that if you use NS_SCHED_THREAD, and the procedure is still active the next time to run occurs, the next run is skipped instead of just delayed.</p>
<p><a name="289921">
</a>The <code>interval</code> is the number of seconds between runs of the procedure.</p>
<p><a name="289922">
</a>The <code>cleanup</code> procedure will be run once when the <code>proc</code> procedure is unscheduled.</p>
