CLC_ErrorCode Parameter_DeclareParameterChanged	(	CPHOBJECT const	hParameter,
		CPUINT16 const	wIndex,
		CPUINT16 const	wRawValue
	)

This can be used to declare a parameter value change without sending immediately the feedback. Then the CHAI can call the IInput_ParameterNotificationHandler::OnParameter_RequestCurrentValue when it deems it necessary. This is a convenient way to limit the bandwidth used by parameter's current value feedback.

Remarks

The change declaration is supported only if the new value is different than the actual current value.

Parameters

[in]	hParameter	Parameter handle.
[in]	wIndex	the related parameter index, or 0 if the parameter is not indexed.
[in]	wRawValue	the new value if the parameter is related to a Modifier or a Selector. This argument is not used in case of Text parameter.

Returns

Standard CHAILink Client return code. See CLC_ErrorCode enumeration.

Warning

This function can only be called in CopperLan context. This means in the pseudo task CPDoProcess(), in notification handlers or in asynchronous return handlers and not in SystemDoProcess() for instance.
