+# libc - Raw FFI bindings to platforms' system libraries
+
+[![GHA Status]][GitHub Actions] [![Cirrus CI Status]][Cirrus CI] [![Latest Version]][crates.io] [![Documentation]][docs.rs] ![License]
+
+`libc` provides all of the definitions necessary to easily interoperate with C
+code (or "C-like" code) on each of the platforms that Rust supports. 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/HEAD/text/1291-promote-libc.md
+
+## v0.3 Roadmap
+
+The main branch is now for v0.3 which has some breaking changes.
+
+For v0.2, please submit PRs to the `libc-0.2` branch instead.
+We will stop making new v0.2 releases once we release v0.3 on crates.io.
+
+See the [tracking issue](https://github.com/rust-lang/libc/issues/3248) for details.
+
+## 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.
+  If you use Rust >= 1.62, this feature is implicitly enabled.
+  Otherwise it requires a nightly rustc.
+
+* **deprecated**: `use_std` is deprecated, and is equivalent to `std`.
+
+## Rust version support
+
+The minimum supported Rust toolchain version is currently **Rust 1.13.0**.
+(libc does not currently have any policy regarding changes to the minimum
+supported Rust version; such policy is a work in progress.) 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 |
+| `const-extern-fn`    |  1.62.0 |
+
+## Platform support
+
+You can see the platform(target)-specific docs on [docs.rs], select a platform you want to see.
+
+See
+[`ci/build.sh`](https://github.com/rust-lang/libc/blob/HEAD/ci/build.sh)
+for the platforms on which `libc` is guaranteed to build for each Rust
+toolchain. The test-matrix at [GitHub Actions] and [Cirrus CI] show the
+platforms in which `libc` tests are run.
