在C++中,可以通过引入DBus库来实现与DBus协议的交互,从而实现在不同进程之间进行高效、可靠的数据传输。 【2.新方法调用:new_method_call】 在C++中,DBus方法调用是通过接口实现的。为了调用一个新的方法,可以使用DBus库中的new_method_call方法。该方法接收三个参数:接口名称、方法名称和参数列表。以下是一个示例...
DBusHandlerResulthandle_player( DBusConnection *p_conn, DBusMessage *p_from,void*p_this ){if(dbus_message_is_method_call( p_from, DBUS_INTERFACE_INTROSPECTABLE,"Introspect") )returnhandle_introspect_player( p_conn, p_from, p_this );/* here D-Bus method names are associated to an handler...
Not really. If the service is launched because of a method call, the method call will be sent immediately after the service registers its name, so if the object server/interface has not yet been set up, the call will go unanswered. I actually first thought that's what is happening in y...
