-//! a textual and numeric description of the error.

-//! The message is formatted using `strerror()`. \a err may be `0` or outside of
-//! the range of known error codes, and the message returned will contain the
-//! string that `strerror()` uses in these cases.
-//!
-//! \param[in] err The error code, usable as an `errno` value.
-//! \param[in] base A string to prepend to the error description.
-//!
-//! \return A string of the format `"Operation not permitted (1)"` if \a err has
-//!     the value `EPERM` on a system where this is defined to be `1`. If \a
-//!     base is not empty, it will be prepended to this string, separated by a
-//!     colon.
