I am reviewing some driver code, and in it, it's using IoGetDriverObjectExtension( miniport_driverObj , portDriver_entrypoint), and the entry point of driver is the real entrypoint and not the GS, so my question is what's the point of doing this? does this return the driver Extension of miniport or..? and does it have to be the real entrypoint of the port driver ? what will happen if i use the entrypoint of the miniport driver or the gsEntrypoint of port driver?
