| <a name="GAsyncInitable.description"></a><h2>Description</h2> | |
| <p>This is the asynchronous version of <a class="link" href="GInitable.html" title="GInitable"><span class="type">GInitable</span></a>; it behaves the same | |
| in all ways except that initialization is asynchronous. For more details | |
| see the descriptions on <a class="link" href="GInitable.html" title="GInitable"><span class="type">GInitable</span></a>.</p> | |
| <p>A class may implement both the <a class="link" href="GInitable.html" title="GInitable"><span class="type">GInitable</span></a> and <a class="link" href="GAsyncInitable.html" title="GAsyncInitable"><span class="type">GAsyncInitable</span></a> interfaces.</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="GAsyncInitable.html#g-async-initable-new-async" title="g_async_initable_new_async ()"><code class="function">g_async_initable_new_async()</code></a> | |
| directly, or indirectly via a <code class="function">foo_thing_new_async()</code> wrapper. This will call | |
| <a class="link" href="GAsyncInitable.html#g-async-initable-init-async" title="g_async_initable_init_async ()"><code class="function">g_async_initable_init_async()</code></a> under the cover, calling back with <a href="../glib-Standard-Macros.html#NULL:CAPS"><code class="literal">NULL</code></a> and | |
| a set <a href="../glib-Error-Reporting.html#GError"><code class="literal">GError</code></a> on failure.</p> | |
| <p>A typical implementation might look something like this:</p> | |

| <em class="parameter"><code><a class="link" href="GAsyncResult.html#GAsyncReadyCallback" title="GAsyncReadyCallback ()"><span class="type">GAsyncReadyCallback</span></a> callback</code></em>, | |
| <em class="parameter"><code><a href="../glib-Basic-Types.html#gpointer"><span class="type">gpointer</span></a> user_data</code></em>);</pre> | |
| <p>Starts asynchronous initialization of the object implementing the | |
| interface. This must be done before any real use of the object after | |
| initial construction. If the object also implements <a class="link" href="GInitable.html" title="GInitable"><span class="type">GInitable</span></a> you can | |
| optionally call <a class="link" href="GInitable.html#g-initable-init" title="g_initable_init ()"><code class="function">g_initable_init()</code></a> instead.</p> | |
| <p>When the initialization is finished, <em class="parameter"><code>callback</code></em> | |
| will be called. You can | |
| then call <a class="link" href="GAsyncInitable.html#g-async-initable-init-finish" title="g_async_initable_init_finish ()"><code class="function">g_async_initable_init_finish()</code></a> to get the result of the | |
| initialization.</p> | |
| <p>Implementations may also support cancellation. If <em class="parameter"><code>cancellable</code></em> | |
| is not | |
| <a href="../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="../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>As with <a class="link" href="GInitable.html" title="GInitable"><span class="type">GInitable</span></a>, if the object is not initialized, or initialization | |
| returns with an error, then all operations on the object except | |
| <a href="../gobject-The-Base-Object-Type.html#g-object-ref"><code class="function">g_object_ref()</code></a> and <a href="../gobject-The-Base-Object-Type.html#g-object-unref"><code class="function">g_object_unref()</code></a> are considered to be invalid, and | |
| have undefined behaviour. They will often fail with <a href="../glib-Message-Logging.html#g-critical"><code class="function">g_critical()</code></a> or | |
| <a href="../glib-Message-Logging.html#g-warning"><code class="function">g_warning()</code></a>, but this must not be relied on.</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 it's safe to implement the singleton | |
| pattern in the GObject constructor function.</p> | |
| <p>For classes that also support the <a class="link" href="GInitable.html" title="GInitable"><span class="type">GInitable</span></a> interface, the default | |
| implementation of this method will run the <a class="link" href="GInitable.html#g-initable-init" title="g_initable_init ()"><code class="function">g_initable_init()</code></a> function | |
| in a thread, so if you want to support asynchronous initialization via | |
| threads, just implement the <a class="link" href="GAsyncInitable.html" title="GAsyncInitable"><span class="type">GAsyncInitable</span></a> interface without overriding | |
| any interface methods.</p> | |
