Alex Crichton 87def1fb80 Add intiial support for wasm32-unknown-wasi This target is [being proposed][LINK] int he rust-lang/rust repository and this is intended to get coupled with that proposal. The definitions here all match the upstream reference-sysroot definitions and the functions all match the reference sysroot as well. The linkage here is described more in detail on the Rust PR itself, but in general it's similar to musl. Automatic verification has been implemented in the same manner as other targets, and it's been used locally to develop this PR and catch errors in the bindings already written (also to help match the evolving sysroot of wasi). The verification isn't hooked up to CI yet though because there is no wasi target distributed via rustup just yet, but once that's done I'll file a follow-up PR to execute verification on CI.

libc - Raw FFI bindings to platforms' system libraries

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.

Usage

Add the following to your Cargo.toml:

[dependencies]
libc = "0.2"

Features

use_std: by default libc links to the standard library. Disable this feature remove this dependency and be able to use libc in #![no_std] crates.
extra_traits: all structs implemented in libc are Copy and Clone. This feature derives Debug, Eq, Hash, and PartialEq.

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

Platform support

Platform-specific documentation (master branch).

See ci/build.sh for the platforms on which libc is guaranteed to build for each Rust toolchain. The test-matrix at Travis-CI, Appveyor, and Cirrus-CI show the platforms in which libc tests are run.
