<h3>Arguments.</h3>

<dl>
<dt><b>oop_source *source</b>
<dd>The event source to use.  The adapter will use this event source to wait
asynchronously for console input.<p>
</dl>

<h3>Description.</h3>

<dl>
<dt><b>oop_readline_register</b>
<dd>Register a liboop <em>source</em> with the
<a href="http://cnswww.cns.cwru.edu/~chet/readline/rltop.html">GNU Readline
Library</a>.  The adapter responds asynchronously to console input and notifies
Readline when it arrives via rl_callback_read_char().  You should use the
Readline <a href="http://cnswww.cns.cwru.edu/~chet/readline/readline.html#SEC38">alternate
interface</a> to prompt the user and receive input.<p>

Note well that Readline will
<a href="http://cnswww.cns.cwru.edu/~chet/readline/readline.html#SEC40">install
its own signal handlers</a> by default.  Make sure to disable this behavior
by setting rl_catch_signals to zero if you wish to manage signals with
liboop.<p>

<dt><b>oop_readline_cancel</b>
<dd>Unregister liboop with Readline.  After this is called,
rl_readback_read_char() will no longer be invoked automatically.<p>
</dl>
