我有一个以 DBus Introspection XML 格式描述的接口:
<!DOCTYPE node PUBLIC "-//freedesktop//DTD D-BUS Object Introspection 1.0//EN"
"http://www.freedesktop.org/standards/dbus/1.0/introspect.dtd">
<node>
<interface name="com.example.foo">
<method name="Bar" />
</interface>
</node>
我像这样运行 gdbus-codegen:
gdbus-codegen --interface-prefix=com.example --generate-c-code=foo-dbus --c-namespace=Dbus foo.xml
我使用这样的代码:
int main()
{
DbusFoo * skeleton = dbus_foo_skeleton_new();
g_object_unref(skeleton);
return 0;
}
但是应用程序最终泄漏了一个生成的信号dbus_foo_default_init()
,如下所示:
static void
dbus_foo_default_init (DbusFooIface *iface)
{
/* GObject signals for incoming D-Bus method calls: */
/**
* DbusFoo::handle-bar:
* @object: A #DbusFoo.
* @invocation: A #GDBusMethodInvocation.
*
* Signal emitted when a remote caller is invoking the <link linkend="gdbus-method-com-example-foo.Bar">Bar()</link> D-Bus method.
*
* If a signal handler returns %TRUE, it means the signal handler will handle the invocation (e.g. take a reference to @invocation and eventually call dbus_foo_complete_bar() or e.g. g_dbus_method_invocation_return_error() on it) and no order signal handlers will run. If no signal handler handles the invocation, the %G_DBUS_ERROR_UNKNOWN_METHOD error is returned.
*
* Returns: %TRUE if the invocation was handled, %FALSE to let other signal handlers run.
*/
g_signal_new ("handle-bar",
G_TYPE_FROM_INTERFACE (iface),
G_SIGNAL_RUN_LAST,
G_STRUCT_OFFSET (DbusFooIface, handle_bar),
g_signal_accumulator_true_handled,
NULL,
g_cclosure_marshal_generic,
G_TYPE_BOOLEAN,

}
我的问题:
使用 gdbus-codegen 生成的代码后如何清理?
