我有監視目錄(/測試)並通知我的程序。 我想改進它來監視另一個目錄(比如/ opt)。 還有如何監控它的子目錄,目前我會收到通知,如果任何更改/測試下的文件。但我沒有得到任何inotifcation如果所做的更改/測試的子目錄,這是觸摸/test/sub-dir/files.txt ..C程序使用inotify監視多個目錄以及子目錄?
這裏我當前的代碼 - 希望這將有助於
/*
Simple example for inotify in Linux.
inotify has 3 main functions.
inotify_init1 to initialize
inotify_add_watch to add monitor
then inotify_??_watch to rm monitor.you the what to replace with ??.
yes third one is inotify_rm_watch()
