//! This crate provides FFI bindings for the [`libcsp` library](https://github.com/libcsp/libcsp).
//! Generally, you probably do not want to use this library directly and instead use the
//! [`libcsp`](https://crates.io/crates/libcsp) Rust crate which provides a safe and ergonomic Rust
//! API.
//!
//! You can find some more high-level information and examples in the
//! [main repository](https://egit.irs.uni-stuttgart.de/rust/libcsp-rust).
//!
//! ## Compile-time configuration
//!
//! This library requires some compile-time configuration file to be included to work
//! properly. You can see an example version of the file for the workspace
//! [here](https://egit.irs.uni-stuttgart.de/rust/libcsp-rust/src/branch/main/examples/autoconfig.rs).
//! The user has to provide the path to a directory containing this `autoconfig.rs` file using the
//! `CSP_CONFIG_DIR` environmental variable.
#![no_std]
#![cfg_attr(docs_rs, feature(doc_auto_cfg))]
#![allow(non_upper_case_globals)]
#![allow(non_camel_case_types)]
#![allow(non_snake_case)]
pub mod config;
// This file will be created by the build script by copying a user-provided file to the output
// directory. It contains important compile time constants. Compilation of the library is not
// possible without these constants.
