PFND3D10DDI_OPENRESOURCE callback function (d3d10umddi.h)
The OpenResource(D3D10) function opens a shared resource.
Syntax
PFND3D10DDI_OPENRESOURCE Pfnd3d10ddiOpenresource;
void Pfnd3d10ddiOpenresource(
D3D10DDI_HDEVICE unnamedParam1,
const D3D10DDIARG_OPENRESOURCE *unnamedParam2,
D3D10DDI_HRESOURCE unnamedParam3,
D3D10DDI_HRTRESOURCE unnamedParam4
)
{...}
Parameters
unnamedParam1
hDevice [in]
A handle to the display device (graphics context).
unnamedParam2
pOpenResource [in]
A pointer to a D3D10DDIARG_OPENRESOURCE structure that describes the parameters that the user-mode display driver uses to open a shared resource.
unnamedParam3
hResource [in]
A handle to the driver's private data for the resource.
unnamedParam4
hRTResource [in]
A handle to the resource that the driver should use anytime it calls back into the Direct3D runtime.
Return value
None
Remarks
The driver can use the pfnSetErrorCb callback function to set an error code.
The driver might run out of memory. Therefore, the driver can pass E_OUTOFMEMORY or D3DDDIERR_DEVICEREMOVED in a call to the pfnSetErrorCb function. The Direct3D runtime will determine that any other errors are critical. If the driver passes any errors, including D3DDDIERR_DEVICEREMOVED, the Direct3D runtime will determine that the handle is invalid; therefore, the runtime will not call the DestroyResource(D3D10) function to destroy the handle that the hResource parameter specifies.
