Hell,
i have a function to implement that returns a pointer to an array
of pixels representing the
pixels in the specified row of the surface columns from x (inclusive) to x +
w
(exclusive), I implemented it like this......
{ void *data;
int pitch;
surface->Lock(surface, DSLF_READ, &data, &pitch );
return (pointer *)data + pitch*row;
}
running this function is aborting the program with this message......
DirectFBError [>surface->Lock( surface, (DFBSurfaceLockFlags)(DSLF_READ |
DSLF_WRITE), &data, &pitch )]: Resource is locked!
