ISpSREngineSite::SetBufferNotifySize (Windows Embedded CE 6.0)
1/6/2010
This method sets the minimum amount of data that should be available before a data available event is set. The engine uses the method only if it calls ISpSREngineSite::Read with at least a certain amount of data available. The engine only calls this method from inside a call to its ISpSREngine::RecognizeStream method, but it can be called on any thread.
This method is used in conjunction with the Win32 event passed as a parameter to ISpSREngine::RecognizeStream. On non-real-time streams, for example, a stream read from a wave file, this event will always be set, as all the data in the file is available for reading. In this case, ISpSREngineSite::SetBufferNotifySize will return SP_UNSUPPORTED_ON_STREAM_INPUT.
Syntax

ULONG cbSize
