(CarbonCore.framework) FSEventStreamFlushSync(): failed assertion '(SInt64)last_id > 0LL'
以下是来自FSEvents.h的方法签名FSEventStreamFlushSync（）
/*
* FSEventStreamFlushSync()
*
* Discussion:
* Asks the FS Events service to flush out any events that have
* occurred but have not yet been delivered, due to the latency
* parameter that was supplied when the stream was created. This
* flushing occurs synchronously -- by the time this call returns,
* your callback will have been invoked for every event that had
* already occurred at the time you made this call.
* FSEventStreamFlushSync() can only be called after the stream has
* been started, via FSEventStreamStart().
*
* Parameters:
*
* streamRef:
* A valid stream.
*
* Availability:
* Mac OS X: in version 10.5 and later in CoreServices.framework
* CarbonLib: not available
* Non-Carbon CFM: not available
