remove an existing watch from an inotify instance
Standard C library (libc, -lc)
inotify_rm_watch() removes the watch associated with the watch descriptor wd from the inotify instance associated with the file descriptor fd.
Removing a watch causes an IN_IGNORED event to be generated for this watch descriptor. (See inotify(7).)
On success, inotify_rm_watch() returns zero. On error, -1 is returned and errno is set to indicate the error.
