Hi Amit,

Please make sure you reply to the list, so all can benefit. :)

This fn requires io_connect_t handle obtained from IOServiceOpen for IOFramebuffer Service. If Window Server has opened it exclusively, then how can I call IOFBGetFramebufferInformationForAperture fn.

The short answer is you can't. IOFramebufferUserClient only supports one client.

Perhaps if you were to explain what your goal is, or why you need the information from IOFBGetFramebufferInformationForAperture, we may be able to come up with an alternate solution.

Cheers,
