如何检测何时使用inotify挂载目录? [英] How could I detect when a directory is mounted with inotify?

问题描述

我正在使用Linux Inotify来检测程序中的FS事件.

I'm using Linux Inotify to detect FS events on my program.

当设备安装在受监视的目录上时，如何通知我?

How could I be notified when a device is mounted on a monitored directory?

推荐答案

我认为您不能使用inotify做到这一点.不过这是方法:

I don't think you can do it with inotify. Here is the method though:

1. 通过不是"mount"的那些套接字.
2. 在获取带有"mount"动作.
3. 使用刚刚安装的设备查找安装点的记录，如果不是正在查看的目录，则将其过滤掉.

1. Read uevents from kernel via a Netlink socket and filter out those where "ACTION" is not "mount".
2. Read and parse "/proc/mounts" when you get an event with a "mount" action.
3. Find a record for a mount point with device that was just mounted and filter it out if it's not the directory you are watching.
