+//! The Unix `fcntl` function is effectively lots of different functions hidden
+//! behind a single dynamic dispatch interface. In order to provide a type-safe
+//! API, rustix makes them all separate functions so that they can have
+//! dedicated static type signatures.
+//!
+//! `fcntl` functions which are not specific to files or directories live in
+//! the [`io`] module instead.
+//!
+//! [`io`]: crate::io
