DefaultConstantBufferUpdateSubresourceUP(D3D11_1) routine

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 DefaultConstantBufferUpdateSubresourceUP(D3D11_1);

VOID APIENTRY* DefaultConstantBufferUpdateSubresourceUP(D3D11_1)(
  D3D10DDI_HDEVICE   hDevice,
  D3D10DDI_HRESOURCE hDstResource,
  UINT               DstSubresource,
  _In_opt_  const D3D10_DDI_BOX      *pDstBox,
  _In_      const VOID               *pSysMemUP,
  UINT               RowPitch,
  UINT               DepthPitch,
  UINT               CopyFlags
)
{ ... }

Parameters

hDevice

A handle to the display device (graphics context).

hDstResource

A handle to the destination resource to copy to.

DstSubresource

An index that indicates the destination subresource to copy to.

pDstBox [in, optional]

A pointer to a D3D10_DDI_BOX structure that specifies the region of the destination subresource to copy data to. If pDstBox is NULL, the driver should copy to the entire destination subresouce.

pSysMemUP [in]

A pointer to the beginning address of the source data that DefaultConstantBufferUpdateSubresourceUP(D3D11_1) uses to update the destination subresouce.

RowPitch

The offset, in bytes, to move to the next row of source data.

DepthPitch

The offset, in bytes, to move to the next depth slice of source data.

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.
