This service call returns various statuses of the eventflag indicated by flgid.
wtskid
Returned to wtskid is the ID number of the task at the top of a waiting queue (the next task to be dequeued). If no
tasks are kept waiting, TSK_NONE is returned.
flgptn
Returned to flgptn is the current eventflag bit pattern.
If this service call is to be issued from task context, use ref_flg; if issued from non-task context, use iref_flg.
