I do it in the following way:

        1. read framebuffer with lrectread to get an image array.
        2. set this image array to a pftexture type variable.
        3. make sure that this pftexture is properly configured to
           receive the above image array.
        4. call pfLoadTex in the DRAW process to load this pfTexture
           into the texture memory.

Hope this helps.
