These service calls cancel the WAITING state (sleeping state) of the task specified by parameter tskid.
As a result, the target task is moved from the sleeping state to the READY state, or from the WAITING-SUSPENDED state to the SUSPENDED state.
If the target task is in a state other than the sleeping state when this service call is issued, this service call does not move the state but increments the wakeup request counter (by added 0x1 to the wakeup request counter).
Note 1 If the target task is moved to the READY state after this service call is issued, this service call also re-queues the task at the end of the ready queue corresponding to the priority of the task.
