updates a destination subresource region that stores constant buffers from a source system-memory region. Implemented by Windows Display Driver Model (WDDM) 1.2 and later user-mode display drivers.

Syntax

PFND3D11_1DDI_RESOURCEUPDATESUBRESOURCEUP Pfnd3d111DdiResourceupdatesubresourceup;

void Pfnd3d111DdiResourceupdatesubresourceup(
   D3D10DDI_HDEVICE,
   D3D10DDI_HRESOURCE,
   UINT,
  CONST D3D10_DDI_BOX *,
  CONST VOID *,
   UINT,
   UINT,
  UINT CopyFlags
)
{...}

Parameters

D3D10DDI_HDEVICE

D3D10DDI_HRESOURCE

UINT

*

UINT

UINT

CopyFlags

A value that specifies characteristics of copy operation as a bitwise OR of the values in the D3D11_1_DDI_COPY_FLAGS enumeration type.

Return Value

None.

The driver can use the pfnSetErrorCb callback function to set an error code. For more information about setting error codes, see the following Remarks section.

Remarks

The driver should not encounter any error, except for D3DDDIERR_DEVICEREMOVED. Therefore, if the driver passes any error, except for D3DDDIERR_DEVICEREMOVED, in a call to the pfnSetErrorCb function, the Direct3D runtime will determine that the error is critical. Even if the device was removed, the driver is not required to return D3DDDIERR_DEVICEREMOVED; however, if device removal interfered with the operation of DefaultConstantBufferUpdateSubresourceUP(D3D11_1) (which typically should not happen), the driver can return D3DDDIERR_DEVICEREMOVED.
