GInitable is implemented by

<div class="refsect1" title="Description">
<a name="GInitable.description"></a><h2>Description</h2>
<p>
<a class="link" href="GInitable.html" title="GInitable"><span class="type">GInitable</span></a> is implemented by objects that can fail during
initialization. If an object implements this interface the
<a class="link" href="GInitable.html#g-initable-init" title="g_initable_init ()"><code class="function">g_initable_init()</code></a> function must be called as the first thing
after construction. If <a class="link" href="GInitable.html#g-initable-init" title="g_initable_init ()"><code class="function">g_initable_init()</code></a> is not called, or if
it returns an error, all further operations on the object
should fail, generally with a <a class="link" href="gio-GIOError.html#G-IO-ERROR-NOT-INITIALIZED:CAPS"><code class="literal">G_IO_ERROR_NOT_INITIALIZED</code></a> error.
</p>
<p>
Users of objects implementing this are not intended to use
the interface method directly, instead it will be used automatically
in various ways. For C applications you generally just call
<a class="link" href="GInitable.html#g-initable-new" title="g_initable_new ()"><code class="function">g_initable_new()</code></a> directly, or indirectly via a <code class="function">foo_thing_new()</code> wrapper.
This will call <a class="link" href="GInitable.html#g-initable-init" title="g_initable_init ()"><code class="function">g_initable_init()</code></a> under the cover, returning <a href="/usr/share/gtk-doc/html/glib/glib-Standard-Macros.html#NULL:CAPS"><code class="literal">NULL</code></a> and
setting a <a href="/usr/share/gtk-doc/html/glib/glib-Error-Reporting.html#GError"><code class="literal">GError</code></a> on failure.
</p>
<p>
For bindings in languages where the native constructor supports
exceptions the binding could check for objects implemention <a class="link" href="GInitable.html" title="GInitable"><code class="literal">GInitable</code></a>
during normal construction and automatically initialize them, throwing
an exception on failure.

<p>
Initializes the object implementing the interface. This must be
done before any real use of the object after initial construction.
</p>
<p>
Implementations may also support cancellation. If <em class="parameter"><code>cancellable</code></em> is not <a href="/usr/share/gtk-doc/html/glib/glib-Standard-Macros.html#NULL:CAPS"><code class="literal">NULL</code></a>,
then initialization can be cancelled by triggering the cancellable object
from another thread. If the operation was cancelled, the error
<a class="link" href="gio-GIOError.html#G-IO-ERROR-CANCELLED:CAPS"><code class="literal">G_IO_ERROR_CANCELLED</code></a> will be returned. If <em class="parameter"><code>cancellable</code></em> is not <a href="/usr/share/gtk-doc/html/glib/glib-Standard-Macros.html#NULL:CAPS"><code class="literal">NULL</code></a> and
the object doesn't support cancellable initialization the error
<a class="link" href="gio-GIOError.html#G-IO-ERROR-NOT-SUPPORTED:CAPS"><code class="literal">G_IO_ERROR_NOT_SUPPORTED</code></a> will be returned.
</p>
<p>
If this function is not called, or returns with an error then all
operations on the object should fail, generally returning the
error <a class="link" href="gio-GIOError.html#G-IO-ERROR-NOT-INITIALIZED:CAPS"><code class="literal">G_IO_ERROR_NOT_INITIALIZED</code></a>.
</p>
<p>
Implementations of this method must be idempotent, i.e. multiple calls
to this function with the same argument should return the same results.
Only the first call initializes the object, further calls return the result
of the first call. This is so that its safe to implement the singleton
pattern in the GObject constructor function.
