//! `libpam-sys` provides low-level access to LibPAM.
//!
//! Everything in here is directly as exported from the LibPAM library or
//! its header files, with two exceptions:
//!
//! - The [`pam_impl`] submodule (and the associated [`pam_impl_name!`] macro),
//!   which can be used to detect the current PAM implementation.
//! - The [`aliases`] submodule, which contains convenient aliases
//!   for callback types used in libpam, so you don't have to type
//!   `unsafe extern "C" fn(this is so long)` all the time.
#![doc = concat!("This documentation was built for the **", pam_impl_name!(), "** implementation.")]
//!
//! You can override this **at build time** by setting the `LIBPAMSYS_IMPL`
//! environment variable to one of the values of the [`pam_impl::PamImpl`] enum.
//! For more information about configuration, see the documentation of
//! [`libpam-sys-impls`](https://crates.io/crates/libpam-sys-impls).
