	)

Allocates a calculation handler for the ports of a main ID of the GV node.
Free the allocated handler with FreeCalculationHandler().

Parameters

[in]	main_id	The main ID.
[in]	calc	The calculation helper. The caller owns the pointed calculation helper.
[in]	run	The run helper. The caller owns the pointed run helper.
[in]	singleport	The port index if the handler should be for a specific port. Otherwise pass GV_MULTIPLE_PORTS.

Returns

The allocated handler, or nullptr if failed.

FreeCalculationHandler()

void FreeCalculationHandler

(

GvValue *&

value

)

Frees calculation handlers allocated with AllocCalculationHandler().

Parameters

[in,out]

value

The calculation handler to free. Set to nullptr afterwards.

CalculateRawData()

Bool CalculateRawData	(	GvValueID	value_id,
		const void *const	data1,
		const void *const	data2,
		void *	dest,
		GvValueFlags	calculation,
		Float	parm1
	)

Convenience function to do calculation with unknown data.
Retrieves the handler for value_id and then calls GV_VALUE_HANDLER::Calculate(userdata, value_id, data1, data2, dest, 0, calculation, parm1).

See also

GvPort::CalculateRawData() for a similar functionality for ports.

Parameters

[in]	value_id	Determines the type of the data parameters.
[in]	data1	The first data. The caller owns the pointed data. Points to GV data. The layout of the pointed data is determined by value_id.
[in]	data2	The second data. The caller owns the pointed data. Points to GV data. The layout of the pointed data is determined by value_id.
[out]	dest	The destination. The caller owns the pointed data. Points to GV data. The layout of the pointed data is determined by value_id.
[in]	calculation	The calculation to perform: GvValueFlags
[in]	parm1	An additional parameter.

Returns

true if the result of the calculation was GV_CALC_ERR_NONE, otherwise false.
