+constants (e.g., EINVAL) as well as function headers (e.g., malloc).
+
+This crate exports all underlying platform types, functions, and
+constants under the crate root, so all items are accessible as
+@samp{libc::foo}.  The types and values of all the exported APIs match
+the platform that libc is compiled for.")
