<h3>Description.</h3>

<dl>
27
<dt><b>oop_sys_new</b>
28
<dd>Create a new system event source.  The system event source implements the
29
event source interface and manages a select() loop.  Once the system event
30
source is created, use <a href="oop_sys_source">oop_sys_source()</a> to
31
access the event source interface (which lets you register event sinks), and
32
<a href="oop_sys_run">oop_sys_run()</a> or
33
<a href="oop_sys_run">oop_sys_run_once()</a> to actually process events.
34
More than one system event source can exist, though it is rarely useful to do
35
so (since only one may be active at a time).<p>
36
 
37
If a malloc failure occurs creating the system event source, NULL is returned.
38
It is up to the caller to handle this failure.<p>
39
 
40
<dt><b>oop_sys_delete</b>
41
<dd>Destroy the system event source <em>sys</em>.  This frees all resources
42
associated with the event source.  The source cannot have any active callbacks
43
(event sinks) associated with it.<p>
