<a name="InfSaslContext.description"></a><h2>Description</h2>
<p><a class="link" href="InfSaslContext.html" title="InfSaslContext"><span class="type">InfSaslContext</span></a> is a wrapper for the Gsasl library. It basically adds
functionality to provide properties asynchronously to Gsasl, so that for
example a dialog can be shown to the user before continuing with the
authentication process. With Gsasl, it is expected that the callback
function sets the requested property before returning, which makes it hard
to give control back to a main loop while waiting for user input.</p>
<p>This wrapper makes sure the callback is called in another thread so that it
can block without affecting the rest of the program.
Use <a class="link" href="InfSaslContext.html#inf-sasl-context-session-feed" title="inf_sasl_context_session_feed ()"><code class="function">inf_sasl_context_session_feed()</code></a> as a replacement for <code class="function">gsasl_step64()</code>.
Instead of returning the result data directly, the function calls a
callback once all properties requested have been provided.</p>
<p>All threading internals are hidden by the wrapper, so all callbacks are
issued in the user thread. However, it requires an <a class="link" href="InfIo.html" title="InfIo"><span class="type">InfIo</span></a> object to
dispatch messages to it. Also, all <a class="link" href="InfSaslContext.html" title="InfSaslContext"><span class="type">InfSaslContext</span></a> functions are fully
thread-safe.</p>

<pre class="programlisting"><span class="returnvalue">void</span>
<span class="c_punctuation">(</span>*InfSaslContextCallbackFunc<span class="c_punctuation">)</span> (<em class="parameter"><code><a class="link" href="InfSaslContext.html#InfSaslContextSession" title="InfSaslContextSession"><span class="type">InfSaslContextSession</span></a> *session</code></em>,
<em class="parameter"><code><span class="type">Gsasl_property</span> property</code></em>,
<em class="parameter"><code><span class="type">gpointer</span> session_data</code></em>,
<em class="parameter"><code><span class="type">gpointer</span> user_data</code></em>);</pre>
<p>This callback is called whenever a property is required to proceed with
authentication. For example, when a password is required, the callback is
called with <em class="parameter"><code>property</code></em>
set to <code class="literal">GSASL_PASSCODE</code>.</p>
<p>The function is then expected to set that property using
<a class="link" href="InfSaslContext.html#inf-sasl-context-session-set-property" title="inf_sasl_context_session_set_property ()"><code class="function">inf_sasl_context_session_set_property()</code></a> and, once it is done, call
<a class="link" href="InfSaslContext.html#inf-sasl-context-session-continue" title="inf_sasl_context_session_continue ()"><code class="function">inf_sasl_context_session_continue()</code></a>. This can happen fully asynchronously,
that is it does not need to take place directly within the callback but the
callback can, for example, open a dialog for the user to enter a password
and then once the user closes the dialog call the two functions mentioned
above.</p>
