NtGdiDdEndMoCompFrame function

[This function is subject to change with each operating system revision. Instead, use the Microsoft DirectDraw and Microsoft Direct3DAPIs; these APIs insulate applications from such operating system changes, and hide many other difficulties involved in interacting directly with display drivers.]

Completes a decoded frame.

Syntax

DWORD APIENTRY NtGdiDdEndMoCompFrame(
  _In_    HANDLE                 hMoComp,
  _Inout_ PDD_ENDMOCOMPFRAMEDATA puEndFrameData
);

Parameters

hMoComp [in]

Handle to a DD_MOTIONCOMP_LOCAL structure that contains a description of the motion compensation being requested.

puEndFrameData [in, out]

Pointer to a DD_ENDMOCOMPFRAMEDATA structure that contains the information needed to complete the decoded frame.

Return value

NtGdiDdEndMoCompFrame returns one of the following callback codes.

Return code Description
DDHAL_DRIVER_HANDLED
The driver has performed the operation and returned a valid return code for that operation. If this code is DD_OK, DirectDraw or Direct3D proceeds with the function. Otherwise, DirectDraw or Direct3D returns the error code provided by the driver and aborts the function.
DDHAL_DRIVER_NOTHANDLED
The driver has no comment on the requested operation. If the driver is required to have implemented a particular callback, DirectDraw or Direct3D reports an error condition. Otherwise, DirectDraw or Direct3D handles the operation as if the driver callback had not been defined by executing the DirectDraw or Direct3D device-independent implementation.
