<a name="DConfClient.description"></a><h2>Description</h2>
<p>
This is a simple class that allows an application to directly read
from and write to the dconf database. There is also a very simple
mechanism for requesting and receiving notification of changes but
not robust mechanism for dispatching change notifications to multiple
listeners.
</p>
<p>
Most applications probably don't want to access dconf directly and
would be better off using something like <span class="type">GSettings</span>.

<p>
This is the type of the callback given to <a href="DConfClient.html#dconf-client-new"><code class="function">dconf_client_new()</code></a>.
</p>
<p>
This function is called in response to changes occuring to the dconf
database that <em class="parameter"><code>client</code></em> is associated with.
</p>
<p>
<em class="parameter"><code>path</code></em> can either be a key or a dir. If <em class="parameter"><code>path</code></em> is a key then <em class="parameter"><code>items</code></em>
will be empty and the notification should be taken to mean that one
key -- the key named by <em class="parameter"><code>path</code></em> -- may have changed.
</p>
<p>
If <em class="parameter"><code>path</code></em> is a dir and <em class="parameter"><code>items</code></em> is empty then it is an indication that
any key under <em class="parameter"><code>path</code></em> may have changed.
</p>
<p>
Otherwise (if <em class="parameter"><code>items</code></em> is non-empty) then the set of affected keys is
the same as if the watch function had been called multiple times for
each item in the array appended to <em class="parameter"><code>path</code></em>. This includes the
possibility of the resulting path being a dir.

Note that in the case of mandatory keys, the result of <a href="DConfClient.html#dconf-client-read-no-default"><code class="function">dconf_client_read_no_default()</code></a> with a fallback
to <a href="DConfClient.html#dconf-client-read-default"><code class="function">dconf_client_read_default()</code></a> is not necessarily the same as the result of a <a href="DConfClient.html#dconf-client-read"><code class="function">dconf_client_read()</code></a>.
This is because the user may have set a value before the key became marked as mandatory, in which
case this call will see the user's (otherwise inaccessible) key.

Cancels the effect of a previous call to <a href="DConfClient.html#dconf-client-watch"><code class="function">dconf_client_watch()</code></a>.
</p>
<p>
If the same path has been watched multiple times then only one of the watches is cancelled and the
net effect is that the path is still watched.
</p>
<p>
This function blocks until the watch has definitely been removed from the bus daemon. It is possible
that notifications in transit will arrive after this call returns. For an asynchronous version of
this call, see <a href="DConfClient.html#dconf-client-unwatch-async"><code class="function">dconf_client_unwatch_async()</code></a>.
