The DefaultConstantBufferUpdateSubresourceUP function updates a destination subresource region that stores constant buffers from a source system-memory region.
unnamedParam1hDevice [in]
A handle to the display device (graphics context).
unnamedParam2hDstResource [in]
A handle to the destination resource to copy to.
unnamedParam3DstSubresource [in]
An index that indicates the destination subresource to copy to.
unnamedParam4pDstBox [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 subresource.
unnamedParam5pSysMemUP [in]
A pointer to the beginning address of the source data that DefaultConstantBufferUpdateSubresourceUP uses to update the destination subresource.
unnamedParam6RowPitch [in]
The offset, in bytes, to move to the next row of source data.
unnamedParam7DepthPitch [in]
The offset, in bytes, to move to the next depth slice of source data.
The driver can use the pfnSetErrorCb callback function to set an error code.
For more information about DefaultConstantBufferUpdateSubresourceUP, see the Remarks section of the ResourceUpdateSubresourceUP function.
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 (which typically should not happen), the driver can return D3DDDIERR_DEVICEREMOVED.
