The OpenResource function informs the driver that a shared resource is opened.
A handle to the display device (graphics context) that is used to open the resource.
pResource [in, out]
A pointer to a D3DDDIARG_OPENRESOURCE structure that describes the resource that is opened.
OpenResource returns S_OK or an appropriate error result if the resource is not successfully opened.
The Microsoft Direct3D runtime calls the user-mode display driver's OpenResource function to inform the user-mode display driver that a shared resource is opened. The driver should store any information that is required to describe the resource and return a unique handle in the hResource member of the D3DDDIARG_OPENRESOURCE structure (pointed to by the pResource parameter) that identifies the new resource in subsequent calls that the Direct3D runtime makes to the driver. The private driver data that is passed to OpenResource is the same private driver data that was passed to the display miniport driver's DxgkDdiCreateAllocation function when the resource was created.
