◆ EGRP_CNT_ERROR

#define EGRP_CNT_ERROR	(	err,
		escope,
		egrp_cnt,
		fmt,
		...
	)

Value:

        INTERNAL_ERROR((err), (escope), \
                       fmt "\n  post_cnt:%u gen:%u applied:%s\n", \
                       ##__VA_ARGS__, \
                       (uint32_t)(egrp_cnt).post_cnt, (uint32_t)(egrp_cnt).gen, \
                       (egrp_cnt).applied ? "true" : "false")

Error reporting macro for event group counters in non-safe mode (only .post_cnt)

◆ event_group_term()

◆ send_ctrl_queue()

em_status_t send_ctrl_queue	(	em_event_t	event,
		em_queue_t	queue,
		em_event_group_t	event_group
	)

Send an internal control event to an EM unscheduled control queue, tagged to an event group.

Internal counterpart to em_send_group() for EM's own control-event plumbing: the per-core/shared unscheduled ctrl queues are dispatched by EM, so the event group count is decremented normally. Unlike em_send_group() this skips the user-facing argument checks, the unscheduled-queue restriction and the user API send-hooks. The caller must pass valid internal arguments.

Returns: EM_OK if successful.
