PFND3DDDI_DESTROYDEVICE callback function (d3dumddi.h)
The DestroyDevice function destroys a graphics context.
Syntax
PFND3DDDI_DESTROYDEVICE Pfnd3dddiDestroydevice;
HRESULT Pfnd3dddiDestroydevice(
HANDLE hDevice
)
{...}
Parameters
hDevice
A handle to the display device (graphics context) being destroyed.
Return value
DestroyDevice returns S_OK or an appropriate error result.
Remarks
The driver should free all of the resources that it allocated for the device and clean up any internal tracking data structures.
Before the driver calls the pfnDeallocateCb function to release allocations, the driver must ensure that the allocations are unlocked. In other words, in the lifetime of a device, every call to the pfnLockCb function to lock an allocation must be paired with a call to the pfnUnlockCb function to unlock the allocation. However, in one call to pfnUnlockCb, the driver can unlock multiple allocations that were each allocated in separate pfnLockCb calls.
