// A portable and thread-safe alternative to C89's `strerror`. // // The C89 specification of `strerror` is not suitable for use in a // multi-threaded application as the returned string may be changed by calls to // `strerror` from another thread. The many non-stdlib alternatives differ // enough in their names, availability, and semantics to justify this wrapper // around them. `errno` will not be modified by a call to `absl::StrError`.
