| <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="/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 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. |
