Outline

Forcibly resume suspended task.

C format

 ER      frsm_tsk (ID tskid);

 ER      ifrsm_tsk (ID tskid);

Parameter(s)

I/O	Parameter	Description
I	ID tskid;	ID number of the task to be resumed.

Explanation

These service calls cancel all of the suspend requests issued for the task specified by parameter tskid (by setting the suspend request counter to 0x0). As a result, the target task moves from the SUSPENDED state to the READY state, or from the WAITING-SUSPENDED state to the WAITING state.

Note This service call does not perform queuing of cancellation requests. If the target task is in a state other than the SUSPENDED or WAITING-SUSPENDED state, "E_OBJ" is therefore returned.
