<P>

In addition to the connection to the X server, an Xlib implementation
may require connections to other kinds of servers (for example, to
input method servers as described in "<A HREF="../localization/">Locales and Internationalized Text Functions</A>").  Toolkits and clients
that use multiple displays, or that use displays in combination with
other inputs, need to obtain these additional connections to correctly
block until input is available and need to process that input
when it is available.  Simple clients that use a single display and
block for input in an Xlib event function do not need to use these
facilities.

<P>

To track internal connections for a display, use
<B><A HREF="XAddConnectionWatch.html">XAddConnectionWatch()</A></B>.

<P>
To stop tracking internal connections for a display, use
<B><A HREF="XRemoveConnectionWatch.html">XRemoveConnectionWatch()</A></B>.

<P>

To process input on an internal connection, use
<B><A HREF="XProcessInternalConnection.html">XProcessInternalConnection()</A></B>.

<P>

To obtain all of the current internal connections for a display, use
<B><A HREF="XInternalConnectionNumbers.html">XInternalConnectionNumbers()</A></B>.
