This method handles an engine extension call to the SR engine. It behaves the same way as ISpSREngine::PrivateCall, except that it allows the engine to retrieve a data block of variable size for the engine extension object.
HRESULT PrivateCallEx( void* pvEngineContext, const void* pInCallFrame, ULONG ulInCallFrameSize, void** ppvCoMemResponse, ULONG* pulResponseSize);
Parameters
- pvEngineContext
[in] Pointer to the speech recognition context for the engine. The pointer is retrieved by a prior call to the ISpSREngine::OnCreateRecoContext method. - pInCallFrame
[in] Pointer to engine-specific input data. - ulInCallFrameSize
[in] Size, in bytes, of the engine-specific data specified by pInCallFrame. - ppvCoMemResponse
[out] Address of a pointer to the response block information from the SR engine. This must be allocated with CoTaskMemAlloc. - pulResponseSize
[out] Pointer to the size, in bytes, of the data specified by ppvCoMemResponse.
