python多线程监控指定目录，主要函数是
win32file.ReadDirectoryChangesW监控目录变化
ReadDirectoryChangesW(handle, size, bWatchSubtree, dwNotifyFilter, overlapped)
retrieves information describing the changes occurring within a directory.
handle : PyHANDLE
Handle to the directory to be monitored. This directory must be opened with the FILE_LIST_DIRECTORY access right.
size : int
Size of the buffer to allocate for the results.
bWatchSubtree : int
Specifies whether the ReadDirectoryChangesW function will monitor the directory or the directory tree. If TRUE is specified, the function monitors the directory tree rooted at the specified directory. If FALSE is specified, the function monitors only the directory specified by the hDirectory parameter.
dwNotifyFilter : int
Specifies filter criteria the function checks to determine if the wait operation has completed. This parameter can be one or more of the FILE_NOTIFY_CHANGE_* values.
overlapped=None : PyOVERLAPPED
An overlapped object. The directory must also be opened with FILE_FLAG_OVERLAPPED.
