 Okay, so now we have a working listener but it's currently not listening to any event. We can now attach any event to that listener:
 <syntaxhighlight lang=c>
-gBool geventAttachSource(GListener *pl, GSourceHandle gsh, unsigned flags);
+gBool geventAttachSource(GListener* pl, GSourceHandle gsh, gU32 flags);
 </syntaxhighlight>
 And now we're ready to take off. We can now use the <code>geventEventWait()</code> routine to wait for an event:
 <syntaxhighlight lang=c>
-GEvent* geventEventWait(GListener *pl, systime_t timeout);
+GEvent* geventEventWait(GListener* pl, gDelay timeout);
 </syntaxhighlight>
 Please note that the <code>geventEventWait()</code> routine is a polling routine (therefore the timeout parameter). Furthermore, the current implementation of GEVENT does not provide an event queue. An event which is triggered while you are not listening for events using <code>geventEventWait()</code> will simply be skipped. The reason to implement this behavior can be found in the memory and CPU usage of such a system. However, GEVENT is not meant for critical event tasks but only for user space applications.

 The GEVENT module is a very powerful event system. It provides a way to create a '''many-to-many''' relationships between sources and listeners. This allows to create user interfaces which use different hardware controls such as buttons '''AND''' touchscreen inputs at the same time very easily.
