transferBuffer() [1/2]

template<typename T >

size_t transferBuffer	(	IDirectArraySourceBuffer< T > &	source,
		DiskBuffer< T > &	target,
		bool	incrementPosition = true,
		size_t	samplesCount = (std::numeric_limits<size_t>::max)()
	)

Transferring data from source buffer to disk buffer without intermediate buffer.

Parameters

source	source buffer
target	disk buffer as target
incrementPosition	an option if change position
samplesCount	a number of samples to be transferred

Returns

number of transferred samples
