This +includes type definitions (e.g. `c_int`), constants (e.g. `EINVAL`) as well as +function headers (e.g. `malloc`). + +This crate exports all underlying platform types, functions, and constants under +the crate root, so all items are accessible as `libc::foo`. The types and values +of all the exported APIs match the platform that libc is compiled for. + +More detailed information about the design of this library can be found in its +[associated RFC][rfc]. + +[rfc]: https://github.com/rust-lang/rfcs/blob/master/text/1291-promote-libc.md + +## Usage + +Add the following to your `Cargo.toml`: + +```toml +[dependencies] +libc = "0.2" +``` + +## Features + +* `std`: by default `libc` links to the standard library. Disable this + feature to remove this dependency and be able to use `libc` in `#![no_std]` + crates. + +* `extra_traits`: all `struct`s implemented in `libc` are `Copy` and `Clone`. + This feature derives `Debug`, `Eq`, `Hash`, and `PartialEq`. + +* `const-extern-fn`: Changes some `extern fn`s into `const extern fn`s. + This feature requires a nightly rustc. + +* **deprecated**: `use_std` is deprecated, and is equivalent to `std`. + +## Rust version support + +The minimum supported Rust toolchain version is **Rust 1.13.0** . APIs requiring +newer Rust features are only available on newer Rust toolchains: + +| Feature | Version | +|----------------------|---------| +| `union` | 1.19.0 | +| `const mem::size_of` | 1.24.0 | +| `repr(align)` | 1.25.0 | +| `extra_traits` | 1.25.0 | +| `core::ffi::c_void` | 1.30.0 | +| `repr(packed(N))` | 1.33.0 | +| `cfg(target_vendor)` | 1.33.0 | + +## Platform support + +[Platform-specific documentation (master branch)][docs.master]. + +See +[`ci/build.sh`](https://github.com/rust-lang/libc/blob/master/ci/build.sh) +for the platforms on which `libc` is guaranteed to build for each Rust +toolchain.
