This service call finds the number of task activation requests enqueued for the task indicated by tskid, returns the result as a
return parameter, and at the same time invalidates all of the task’s activation requests.
Specifying tskid=TSK_SELF(0) specifies the issuing task itself. If TSK_SELF is specified for tskid in non-task context,
operation of this service call cannot be guaranteed.
This service call can be invoked for a task in DORMANT state as the target task. In that case, the return parameter is 0.
If this service call is to be issued from task context, use can_act; if issued from non-task context, use ican_act.
