BuffHandle engine::ProcNode::pull	(	State &	currentProcess,
		uint	requestedOutputNr = 0
	)			const [inline]

Engine Core operation: render and pull output from this node.

On return, currentProcess will hold onto output buffer(s) containing the calculated result frames. In case this node calculates a multichannel output, only one channel can be retrieved by such a pull() call, but you can expect data of the other channels to be processed and fed to cache.

Parameters:

	currentProcess	the current processing state for managing buffers and accessing current parameter values
	requestedOutputNr	the output channel requested (in case this node delivers more than one output channel)

Returns:

handle to the buffer containing the calculated result.
