  22. MonitorDir——windows(ReadDirectoryChangesW)，macos(FSEvents) and linux(fanotify和inotify) Simple example of directory monitoring;
    1. fanotifyused inglobalmode, infanotify_markJoin inFAN_MARK_FILESYSTEM(needCAP_SYS_ADMINability, that is, root permissions) thisflag, all events on the specified file system will be monitored, and then the required events can be filtered according to the specified monitored folder directory. This function is better thaninotifymore powerful;
      1. To obtain the upper-level path where the event file is located, useopen_by_handle_atThis method will appear under ordinary usersOperation not permittedError, also neededCAP_SYS_ADMINAbility, i.e. root authority;
      2. It is recommended to run with root privileges. If you must run it under an ordinary user, it is still recommended to useinotifyinstead offanotify, anyway, opening a monitoring file descriptor (fd), it is impossible to achievesubtreemonitor;
