void AppLayerDecoderEventsSetEvent	(	Flow *	f,
		uint8_t	event
	)

Set an app layer decoder event.

Parameters

f	Pointer to a flow containing DecoderEvents pointer head. If the head points to a DecoderEvents instance, a new instance would be created and the pointer head would would be updated with this new instance
event	The event to be stored.

void AppLayerDecoderEventsSetEventRaw	(	AppLayerDecoderEvents **	sevents,
		uint8_t	event
	)

Set an app layer decoder event.

Parameters

sevents	Pointer to a AppLayerDecoderEvents pointer. If *sevents is NULL memory will be allocated.
event	The event to be stored.
