| <p>The <a class="link" href="GDBusConnection.html" title="GDBusConnection"><span class="type">GDBusConnection</span></a> type is used for D-Bus connections to remote |
| peers such as a message buses. It is a low-level API that offers a |
| lot of flexibility. For instance, it lets you establish a connection |
| over any transport that can by represented as an <a class="link" href="GIOStream.html" title="GIOStream"><span class="type">GIOStream</span></a>.</p> |
| <p>This class is rarely used directly in D-Bus clients. If you are writing |
| a D-Bus client, it is often easier to use the <a class="link" href="gio-Owning-Bus-Names.html#g-bus-own-name" title="g_bus_own_name ()"><code class="function">g_bus_own_name()</code></a>, |
| <a class="link" href="gio-Watching-Bus-Names.html#g-bus-watch-name" title="g_bus_watch_name ()"><code class="function">g_bus_watch_name()</code></a> or <a class="link" href="GDBusProxy.html#g-dbus-proxy-new-for-bus" title="g_dbus_proxy_new_for_bus ()"><code class="function">g_dbus_proxy_new_for_bus()</code></a> APIs.</p> |
| <p>As an exception to the usual GLib rule that a particular object must not |
| be used by two threads at the same time, <a class="link" href="GDBusConnection.html" title="GDBusConnection"><span class="type">GDBusConnection</span></a>'s methods may be |
| called from any thread. This is so that <a class="link" href="GDBusConnection.html#g-bus-get" title="g_bus_get ()"><code class="function">g_bus_get()</code></a> and <a class="link" href="GDBusConnection.html#g-bus-get-sync" title="g_bus_get_sync ()"><code class="function">g_bus_get_sync()</code></a> |
| can safely return the same <a class="link" href="GDBusConnection.html" title="GDBusConnection"><span class="type">GDBusConnection</span></a> when called from any thread.</p> |
| <p>Most of the ways to obtain a <a class="link" href="GDBusConnection.html" title="GDBusConnection"><span class="type">GDBusConnection</span></a> automatically initialize it |
| (i.e. connect to D-Bus): for instance, <a class="link" href="GDBusConnection.html#g-dbus-connection-new" title="g_dbus_connection_new ()"><code class="function">g_dbus_connection_new()</code></a> and |
| <a class="link" href="GDBusConnection.html#g-bus-get" title="g_bus_get ()"><code class="function">g_bus_get()</code></a>, and the synchronous versions of those methods, give you an |
| initialized connection. Language bindings for GIO should use |
| <a class="link" href="GInitable.html#g-initable-new" title="g_initable_new ()"><code class="function">g_initable_new()</code></a> or <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>, which also initialize the |
| connection.</p> |
| <p>If you construct an uninitialized <a class="link" href="GDBusConnection.html" title="GDBusConnection"><span class="type">GDBusConnection</span></a>, such as via |
| <a href="../gobject-The-Base-Object-Type.html#g-object-new"><code class="function">g_object_new()</code></a>, you must initialize it via <a class="link" href="GInitable.html#g-initable-init" title="g_initable_init ()"><code class="function">g_initable_init()</code></a> or |
| <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> before using its methods or properties. |
| Calling methods or accessing properties on a <a class="link" href="GDBusConnection.html" title="GDBusConnection"><span class="type">GDBusConnection</span></a> that has not |
| completed initialization successfully is considered to be invalid, and leads |
| to undefined behaviour. In particular, if initialization fails with a |
| <a href="../glib-Error-Reporting.html#GError"><span class="type">GError</span></a>, the only valid thing you can do with that <a class="link" href="GDBusConnection.html" title="GDBusConnection"><span class="type">GDBusConnection</span></a> is to |
| free it with <a href="../gobject-The-Base-Object-Type.html#g-object-unref"><code class="function">g_object_unref()</code></a>.</p> |

| <p>Adds a message filter. Filters are handlers that are run on all |
| incoming and outgoing messages, prior to standard dispatch. Filters |
| are run in the order that they were added. The same handler can be |
| added as a filter more than once, in which case it will be run more |
| than once. Filters added during a filter callback won't be run on |
| the message being processed. Filter functions are allowed to modify |
| and even drop messages.</p> |
| <p>Note that filters are run in a dedicated message handling thread so |
| they can't block and, generally, can't do anything but signal a |
| worker thread. Also note that filters are rarely needed - use API |
| such as <a class="link" href="GDBusConnection.html#g-dbus-connection-send-message-with-reply" title="g_dbus_connection_send_message_with_reply ()"><code class="function">g_dbus_connection_send_message_with_reply()</code></a>, |

| <p>If a filter consumes an incoming message the message is not |

| (that API such as <a class="link" href="GDBusConnection.html#g-dbus-connection-signal-subscribe" title="g_dbus_connection_signal_subscribe ()"><code class="function">g_dbus_connection_signal_subscribe()</code></a> and |

| <p>Virtual table for handling properties and method calls for a D-Bus |
| interface.</p> |
| <p>Since 2.38, if you want to handle getting/setting D-Bus properties |
| asynchronously, give <a href="../glib-Standard-Macros.html#NULL:CAPS"><code class="literal">NULL</code></a> as your <code class="function">get_property()</code> or <code class="function">set_property()</code> |
| function. The D-Bus call will be directed to your <em class="parameter"><code>method_call</code></em> |
| function, |
| with the provided <em class="parameter"><code>interface_name</code></em> |
| set to "org.freedesktop.DBus.Properties".</p> |
| <p>Ownership of the <a class="link" href="GDBusMethodInvocation.html" title="GDBusMethodInvocation"><span class="type">GDBusMethodInvocation</span></a> object passed to the |
| <code class="function">method_call()</code> function is transferred to your handler; you must |
| call one of the methods of <a class="link" href="GDBusMethodInvocation.html" title="GDBusMethodInvocation"><span class="type">GDBusMethodInvocation</span></a> to return a reply |
| (possibly empty), or an error. These functions also take ownership |
| of the passed-in invocation object, so unless the invocation |
| object has otherwise been referenced, it will be then be freed. |
| Calling one of these functions may be done within your |
| <code class="function">method_call()</code> implementation but it also can be done at a later |
| point to handle the method asynchronously.</p> |
| <p>The usual checks on the validity of the calls is performed. For |
| <code class="literal">Get</code> calls, an error is automatically returned if the property does |
| not exist or the permissions do not allow access. The same checks are |
| performed for <code class="literal">Set</code> calls, and the provided value is also checked for |
| being the correct type.</p> |
| <p>For both <code class="literal">Get</code> and <code class="literal">Set</code> calls, the <a class="link" href="GDBusMethodInvocation.html" title="GDBusMethodInvocation"><span class="type">GDBusMethodInvocation</span></a> |
| passed to the <em class="parameter"><code>method_call</code></em> |
| handler can be queried with |
| <a class="link" href="GDBusMethodInvocation.html#g-dbus-method-invocation-get-property-info" title="g_dbus_method_invocation_get_property_info ()"><code class="function">g_dbus_method_invocation_get_property_info()</code></a> to get a pointer |
| to the <a class="link" href="gio-D-Bus-Introspection-Data.html#GDBusPropertyInfo"><span class="type">GDBusPropertyInfo</span></a> of the property.</p> |
| <p>If you have readable properties specified in your interface info, |
| you must ensure that you either provide a non-<a href="../glib-Standard-Macros.html#NULL:CAPS"><code class="literal">NULL</code></a> <em class="parameter"><code><code class="function">get_property()</code></code></em> |
| |
| function or provide implementations of both the <code class="literal">Get</code> and <code class="literal">GetAll</code> |
| methods on org.freedesktop.DBus.Properties interface in your <em class="parameter"><code>method_call</code></em> |
| |
| function. Note that the required return type of the <code class="literal">Get</code> call is |
| <code class="literal">(v)</code>, not the type of the property. <code class="literal">GetAll</code> expects a return value |
| of type <code class="literal">a{sv}</code>.</p> |
| <p>If you have writable properties specified in your interface info, |
| you must ensure that you either provide a non-<a href="../glib-Standard-Macros.html#NULL:CAPS"><code class="literal">NULL</code></a> <em class="parameter"><code><code class="function">set_property()</code></code></em> |
