Parameter

Description

I

 ID      tskid;
ID number of the task.



Explanation

These service calls move the task specified by parameter tskid from the SUSPENDED state to the READY state, or from the WAITING-SUSPENDED state to the WAITING state.

Note 1 These service calls do not perform queuing of forced cancelation requests. If the target task is neither in the SUSPENDED state nor WAITING-SUSPENDED state, "E_OBJ" is returned.

Note 2 The RI600V4 does not support queuing of suspend request. The behavior of the frsm_tsk and ifrsm_tsk, that can release from the SUSPENDED state even if suspend request has been queued, are same as rsm_tsk and irsm_tsk.
