Notifies the user-mode display driver about the new location of the driver function table.

Implemented by Windows Display Driver Model (WDDM) 1.3 and later user-mode display drivers.

Syntax

PFND3DWDDM1_3DDI_RELOCATEDEVICEFUNCS Pfnd3dwddm13DdiRelocatedevicefuncs;

void Pfnd3dwddm13DdiRelocatedevicefuncs(
  D3D10DDI_HDEVICE unnamedParam1,
  D3DWDDM1_3DDI_DEVICEFUNCS *unnamedParam2
)
{...}

Parameters

unnamedParam1

hDevice [in]

A handle to the display device (graphics context).

unnamedParam2

DeviceFuncs [in]

A pointer to a D3DWDDM1_3DDI_DEVICEFUNCS structure that contains pointers to the functions of the user-mode display driver.

Return value

None

Remarks

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

A user-mode display driver can use the RelocateDeviceFuncs(D3D11_2) function to replace function pointers in the driver function table.
