Hi,
  I am trying to port DirectFB to an embedded system.
In my system, the layer has a viewport and an attached surface. In my
Initlayer function, I associate the layer with its surface.
When an application creates a primary surface, and draws something to it,
how should I get the data from that surface
 to the surface associated with the viewport?
I haven't understood how the primary surface relates to the surface
associated with the layer.
Thanks for your patience,

Regards
Bobby
