    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.

    Parameters

    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.
