InfIo is implemented by
<a class="link" href="InfStandaloneIo.html" title="InfStandaloneIo">InfStandaloneIo</a>.</p>
</div>
<div class="refsect1">
<a name="InfIo.description"></a><h2>Description</h2>
<p>
The <a class="link" href="InfIo.html" title="InfIo"><span class="type">InfIo</span></a> interface is used to schedule timeouts and to watch sockets for
events to occur. An actual implementation usually integrates this into the
application main loop, such as <span class="type">GMainLoop</span>. There is also a standalone
implementation, <a class="link" href="InfStandaloneIo.html" title="InfStandaloneIo"><span class="type">InfStandaloneIo</span></a>, that can directly be used as the
application's main loop.
</p>
<p>
Every object in Libinfinity that needs to schedule timeouts or watches
sockets uses a InfIo to do so. This allows to use libinfinity with
different main event loops, not only Glib's one.
</p>
<p>
<a class="link" href="InfIo.html" title="InfIo"><span class="type">InfIo</span></a> is guaranteed to be thread-safe. All functions can be called from
any thread at any time. However, all callback functions are always called
from the same thread (normally the one running the main loop).
