The D3DDDIARG_BUFFERBLT structure describes the parameters of a buffer bit-block transfer (bitblt) operation.
hDstResource [in]A handle to the destination vertex or index buffer.
hSrcResource [in]A handle to the source vertex or index buffer.
Offset [in]The offset, in bytes, of the destination buffer that the copy should be directed into.
SrcRange [in]A D3DDDIRANGE structure that indicates what range of the source buffer should be copied. This D3DDDIRANGE specifies an offset and size, in bytes.
