ISpSREngine::PrivateCallEx

ISpSREngine::PrivateCallEx performs the same task as ISpSREngine::PrivateCall, except that a variable sized data block can be returned from the engine to the engine extension object.

HRESULT PrivateCallEx(
   void        *pvEngineContext,
   const void  *pInCallFrame,
   ULONG        ulInCallFrameSize,
   void       **ppvCoMemResponse,
   ULONG       *pulResponseSize
 );

Parameters

ulInCallFrameSize

[in] Size, in bytes, of the engine-specific data contained in pInCallFrame.

ppvCoMemResponse
