This function is used by MGDI to notify a driver that the specified PDEVstructure is no longer needed.



Pointer to the PDEVthat describes the physical device to be disabled. This value is the handle returned by the DrvEnablePDEVfunction.


If the driver has been disabled by a call to the DrvEnablePDEVfunction, the driver cannot access the hardware during a call to the DrvDisableSurfacefunction because another active surface might be in use. Any necessary hardware changes should have been performed during the call to the DrvAssertModefunction. A driver should keep track of whether or not it has been disabled by DrvAssertModeso that it can perform proper cleanup operations in DrvDisableSurface.

If the physical device has an enabled surface, the GDI calls this function after calling DrvDisableSurface. The driver should free any memory and resources used by the PDEV.

This function is required for graphics drivers.
