</a><h4>Overview</h4>
<p><a name="81772">
</a>Schedule a procedure to run at specified intervals</p>
<a name="81773">
</a><h4>Syntax</h4>
<p><a name="81774">
</a><b>ns_schedule_proc</b> ?-thread? ?-once? <i>interval </i>{<i>script</i> | <i>procname </i>?<i>args</i>?}</p>
<a name="81775">
</a><h4>Description</h4>
<p><a name="81776">
</a><b>ns_schedule_proc</b> runs the specified Tcl <i>script</i> or procedure (<i>procname</i>) at an interval specified by <i>interval</i>. The <i>interval</i> is the number of seconds between runs of the script.</p>
<p><a name="81777">
</a>Specify -thread if you want a thread created to run the procedure. This will allow the scheduler to continue with other scheduled procedures. Specifying -thread is appropriate in situations where the script will not return immediately, such as when the script performs network activity.</p>
<p><a name="81778">
</a>Specify -once if you want the script to run only one time. The default is that the script will be re-scheduled after each time it is run.</p>
<p><a name="81779">
</a><b>ns_schedule_proc</b> returns an id number for the scheduled procedure that is needed to stop the scheduled procedure with <b>ns_unschedule_proc</b>.</p>
