ISpPrivateEngineCallEx::CallEngineSynchronize

ISpPrivateEngineCallEx::CallEngineSynchronize is used by the engine's extension object to call the main engine object. It has the same functionality as CallEngineEx and returns the non-fixed size data block response information associated with the SR engine.

Applications implementing this method must call CoTaskMemFree to free memory associated with the returned response.

  
    HRESULT CallEngineSynchronize(
   const void    *pInFrame,
   ULONG          ulInFrameSize,
   void         **ppCoMemOutFrame,
   ULONG         *pulOutFrameSize
);

Parameters

  • pInFrame
    [in] Address of the recognition engine data.
  • ulInFrameSize
    [in] Size, in bytes, of the pInFrame structure.
  • ppCoMemOutFrame
    [out] Address of a pointer to the data block information associated with the SR engine.
  • pulOutFrameSize
    [out] Size, in bytes, of the ppCoMemOutFrame structure.
