In DirectX9, how to swap fastly two textures

akira32

LPDIRECT3DTEXTURE9 texture1;
LPDIRECT3DTEXTURE9 texture2;

CreateTexture....

I have a special case and need to swap two textures.
How do I reach the goal to swap them?
If the two textures have the same size and format.

way1:
LPDIRECT3DTEXTURE9 texture3;
texture3=texture1;
texture1=texture2;
texture2=texture3;

way2:
Lock the two textures and memcpy the pBits of the D3DLOCKED_RECT.
But I have a problem how do I know the pBits's size?

Or another way that is fast.

The way1 is enough, only point swap
