Programs that are not required to follow the Ravenscar Profile may also use the predefined packages Ada.Asynchronous_Task_Control, Ada.Dynamic_Priorities, Ada.Synchronous_Task_Control and Ada.Task_Identification.
The function Current_Task allows a task to get an identifier for itself. This identifier may then be used in calls the the subprograms in Ada.Asynchronous_Task_Control, which allow a task to be placed on hold, or to continue. Tasks that are on hold consume no CPU time but do retain their state.
The package Ada.Task_Identification allows a task to be aborted. In M1750 Ada this places the task in a state from which it may be restarted using the subprograms in XGC.Tasking.Stages.
The base priority of any task (including the current task) may be requested or changed using the package Ada.Dynamic_Priorities.
