There is a flag DSDESC_PREALLOCATED to create surface with user data.
//sample
DFBSurfaceDescription desc;
desc.flags = (DFBSurfaceDescriptionFlags)\
(DSDESC_CAPS|DSDESC_WIDTH|DSDESC_HEIGHT|DSDESC_PIXELFORMAT|DSDESC_PREALLOCATED);
desc.caps = DSCAPS_SYSTEMONLY;
desc.pixelformat = some_pix_fmt;
desc.height = height;
desc.width = width;
desc.preallocated[0].data = src; //user data
desc.preallocated[0].pitch = bytes_per_line;
dfb->CreateSurface( dfb, &desc, &ret_surf);
