PN_getLegState()

tLegStates PN_getLegState

(

void

)

Returns the IRT Legacy mode state.

Returns

Current state of the Legacy mode state machine

PN_setLegState()

void PN_setLegState	(	void *	arg,
		void *	arg2
	)

Sets the state of legacy state machine This API is registered as a callback in PN_registerSetState.

Parameters

arg	new state tLegStates
