-//!
-//! \param[in] bp The bootstrap server to check in with.
-//! \param[in] service_name The name of the service to check in.
-//! \param[out] service_port The receive right for the checked-in service.
-//!
-//! \return `BOOTSTRAP_SUCCESS` on success, with \a service_port set
-//!     appropriately. Otherwise, any error that might be returned by
-//!     `bootstrap_check_in()`.
-//!
-//! This function is a wrapper around `bootstrap_check_in()`, checking in with
-//! the bootstrap server at \a bp. It exists primarily for compatibility with
-//! Mac OS X 10.5, where it is not possible to call `bootstrap_check_in()` for a
-//! \a service_name that has not already been registered with the bootstrap
-//! server using `bootstrap_register()`. `bootstrap_register()` was deprecated
-//! in Mac OS X 10.5.
