Parameter(s)


I/O	Parameter	Description
I	ID flgid;	ID number of the eventflag to be set.
I	FLGPTN setptn;	Bit pattern to set (16 bits).

Explanation

These service calls set the result of ORing the bit pattern of the eventflag specified by parameter flgid and the bit pattern specified by parameter setptn as the bit pattern of the target eventflag.

If the required condition of the task queued to the target eventflag wait queue is satisfied when this service call is issued, the relevant task is unlinked from the wait queue at the same time as bit pattern setting processing.

As a result, the relevant task is moved from the WAITING state (waiting state for an eventflag) to the READY state, or from the WAITING-SUSPENDED state to the SUSPENDED state.

Note 1 If the task linked in the wait queue 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.

Note 2 If the bit pattern set to the target eventflag is B'1100 and the bit pattern specified by parameter setptn is B'1010 when this service call is issued, the bit pattern of the target eventflag is set to B'1110.
