<p>This function will indicate to evas that the canvas <code>e</code> is to have all event processing frozen until a matching <a class="el" href="group__Evas__Event__Freezing__Group.html#ga4f08e6b3eece51bf285f1226629924e1" title="Thaw a canvas out after freezing.">evas_event_thaw()</a> function is called on the same canvas. Every freeze call must be matched by a thaw call in order to completely thaw out a canvas.</p>
