AgsApplicationContext:main-loop does usually point to an AgsThread implementing AgsMainLoop interface. libags_thread.so.1 provides you the AgsGenericMainLoop object or if you intend to use libags_audio.so.1, this property shall point to AgsAudioLoop.
As it shall be implemented by AGS_TYPE_THREAD subtypes, this parent object provides
a mutex to properly lock the object. You should obtain the pthread_mutex_t pointer
pthread_mutex_t* ags_mutex_manager_lookup(AgsMutexManager*, GObject*).
The main loop specifies some signals like ::interrupt, ::monitor and ::change-frequency. They are all related to realtime behavior of an application. Assumed you have a thread you want to run within the thread tree, but it is not mandatory to run it. With these functions you can determine if you shall pause your thread during ::interrupt signal. How many time you are allowed to consume or running at all, can be concluded by using ::monitor. In order to get notified about modified refreshing rate of your thread, listen to ::change-frequency signal.
The interface provides some other function pointers. If you want to provide AgsTaskThread
to your application, use
void ags_main_loop_set_async_queue(AgsMainLoop*, GObject*)
To control the AgsThread::clock signal AgsMainLoop's methods are going to be invoked. The involved functions are:
void ags_main_loop_set_tic(AgsMainLoop*, guint)
void ags_main_loop_set_last_sync(AgsMainLoop*, guint)
