	///
	/// * `EINVAL`: An unsupported value was specified in `flags`.
	/// * `EMFILE`: The per-process limit on the number of open file descriptors has been reached.
	/// * `ENFILE`: The system-wide limit on the total number of open files has been reached.
	/// * `ENOMEM`: There was insufficient kernel memory to create the inotify data structures.

	/// Since Linux 2.6.27.
