pfnSetErrorCb routine

The pfnSetErrorCb function sets the return error code of a user-mode display driver's function.

Syntax


PFND3D10DDI_SETERROR_CB pfnSetErrorCb;

void APIENTRY pfnSetErrorCb(
  _In_ D3D10DDI_HRTCORELAYER hRuntimeDevice,
  _In_ HRESULT               hResult
)
{ ... }

Parameters

hRuntimeDevice [in]

A handle to a context for the core Microsoft Direct3D 10 runtime. This handle is supplied to the driver in a call to the driver's CreateDevice(D3D10) function.

hResult [in]

An HRESULT value that specifies the error to set for a driver function.

Return value

None

Remarks

A user-mode display driver can call pfnSetErrorCb many times for each driver invocation. For the driver's functions that do not return status codes, the driver uses pfnSetErrorCb to return error information to the Direct3D runtime.

Requirements

Target platform

Desktop

Version

Available in Windows Vista and later versions of the Windows operating systems.
