[directfb-users] surface's Lock() and Unlock()

[Ha Nguyen]

Hi everybody,

Can I ask if a surface's Lock() and Unlock() do actually wait for all
ongoing operations on the surface to be finished? or updated the surface's
buffer from cache (if any)?

Thanks,
Ha Nguyen

It will wait in case the GPU has pending operations.

Flushing cache is up to the system modules surface pool implementation.
