PFND3D10DDI_DESTROYDEVICE callback function (d3d10umddi.h)
The DestroyDevice(D3D10) function destroys the specified device object.
Syntax
PFND3D10DDI_DESTROYDEVICE Pfnd3d10ddiDestroydevice;
void Pfnd3d10ddiDestroydevice(
D3D10DDI_HDEVICE unnamedParam1
)
{...}
Parameters
unnamedParam1
hDevice
A handle to the display device (graphics context). The Microsoft Direct3D runtime will free the memory region that it previously allocated for the object. Therefore, the driver can no longer access this memory region.
Return value
None
Remarks
The driver can use the pfnSetErrorCb callback function to set an error code.
Before the Direct3D runtime calls DestroyDevice(D3D10), it destroys all of the display device's child objects (blend state, resources, and so on).
The driver should not encounter any error, except for D3DDDIERR_DEVICEREMOVED. Therefore, if the driver passes any error, except for D3DDDIERR_DEVICEREMOVED, in a call to the pfnSetErrorCb function, the Direct3D runtime will determine that the error is critical. Even if the device was removed, the driver is not required to return D3DDDIERR_DEVICEREMOVED; however, if device removal interfered with the operation of DestroyDevice(D3D10) (which typically should not happen), the driver can return D3DDDIERR_DEVICEREMOVED.
