hi

I would like to create a kernel that looks like this:

__kernel void Traverse(__global const TreeRoot *root)
{
// perform some operations...
}

Now, I need to copy the whole tree (obviously) to device. But how
can I get back a pointer to device memory when creating buffers
so that I can assemble the tree in device? I am sure this can be
done in CUDA, but so far I have the feeling that it's not possible
with OpenCL.

thanks
