PFND3D11DDI_CHECKDEFERREDCONTEXTHANDLESIZES callback function (d3d10umddi.h)

The CheckDeferredContextHandleSizes function verifies the sizes of the driver-private memory spaces that hold the handle data of deferred context handles.

Syntax

PFND3D11DDI_CHECKDEFERREDCONTEXTHANDLESIZES Pfnd3d11ddiCheckdeferredcontexthandlesizes;

void Pfnd3d11ddiCheckdeferredcontexthandlesizes(
  D3D10DDI_HDEVICE unnamedParam1,
  UINT *pHSizes,
  D3D11DDI_HANDLESIZE *unnamedParam3
)
{...}

Parameters

unnamedParam1

hDevice [in]

A handle to the display device (graphics context).

pHSizes

The size, in bytes, of the array pointed to by pHandleSize.

unnamedParam3

pHandleSize [out, optional]

An array of D3D11DDI_HANDLESIZE structures that describe the handle data of deferred context handles.

Return value

None

Remarks

The driver can use the pfnSetErrorCb callback function to set a critical error code.

The driver is only required to implement CheckDeferredContextHandleSizes if the driver supports the D3D11DDICAPS_COMMANDLISTS_BUILD_2 capability that can be returned in the D3D11DDI_THREADING_CAPS structure from a call to the GetCaps(D3D10_2) function.

For more information about how CheckDeferredContextHandleSizes is used, see Using Context-Local DDI Handles.

The driver's CheckDeferredContextHandleSizes function cannot call the pfnSetErrorCb callback function to set the D3DDDIERR_DEVICEREMOVED error code because CheckDeferredContextHandleSizes is a capability-check type of function. The driver must ensure that it has enough information after device creation to respond to a call to CheckDeferredContextHandleSizes, even in the presence of D3DDDIERR_DEVICEREMOVED.

CheckDeferredContextHandleSizes should not encounter any errors. However, CheckDeferredContextHandleSizes might call pfnSetErrorCb for critical errors.
