PFND3D10DDI_CREATEQUERY callback function (d3d10umddi.h)
The CreateQuery(D3D10) function creates a query.
Syntax
PFND3D10DDI_CREATEQUERY Pfnd3d10ddiCreatequery;
void Pfnd3d10ddiCreatequery(
D3D10DDI_HDEVICE unnamedParam1,
const D3D10DDIARG_CREATEQUERY *unnamedParam2,
D3D10DDI_HQUERY unnamedParam3,
D3D10DDI_HRTQUERY unnamedParam4
)
{...}
Parameters
unnamedParam1
hDevice [in]
A handle to the display device (graphics context).
unnamedParam2
pCreateQuery [in]
A pointer to a D3D10DDIARG_CREATEQUERY structure that describes the parameters that the user-mode display driver uses to create a query.
unnamedParam3
hQuery [in]
A handle to the driver's private data for the query.
unnamedParam4
hRTQuery [in]
A handle to the query 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 or be unable to create queries because of their exclusive nature. Therefore, the driver can pass E_OUTOFMEMORY, DXGI_DDI_ERR_NONEXCLUSIVE, 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 DestroyQuery(D3D10) function to destroy the handle that the hQuery parameter specifies.
