-//! This module provides a macro to define a constant of type
-//! [`CStr`](std::ffi::CStr), for compatibility with versions of
-//! Rust that lack `c""` literals.
-//!
-//! Documentation is hidden because it only exposes macros, which
-//! are exported directly from `qemu_api`.

-/// Given a string constant _without_ embedded or trailing NULs, return
