+libc
+====
+
+A Rust library with native bindings to the types and functions commonly found on
+various systems, including libc.
+
+[![Build Status](https://travis-ci.org/rust-lang/libc.svg?branch=master)](https://travis-ci.org/rust-lang/libc)
+[![Build status](https://ci.appveyor.com/api/projects/status/34csq3uurnw7c0rl?svg=true)](https://ci.appveyor.com/project/alexcrichton/libc)
+
+[Documentation](#platforms-and-documentation)
+
+## Usage
+
+First, add the following to your `Cargo.toml`:
+
+```toml
+[dependencies]
+libc = "0.2"
+```
+
+Next, add this to your crate root:
+
+```rust
+extern crate libc;
+```
+
+Currently libc by default links to the standard library, but if you would
+instead like to use libc in a `#![no_std]` situation or crate you can request
+this via:
+
+```toml
+[dependencies]
+libc = { version = "0.2", default-features = false }
+```
+
+## What is libc?
+
+The primary purpose of this crate is to provide 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 does not strive to have any form of compatibility across platforms,
+but rather it is simply a straight binding to the system libraries on the
+platform in question.
+
+## Public API
+
+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
+
+## Adding an API
+
+Want to use an API which currently isn't bound in `libc`? It's quite easy to add
+one!
+
+The internal structure of this crate is designed to minimize the number of
+`#[cfg]` attributes in order to easily be able to add new items which apply
+to all platforms in the future. As a result, the crate is organized
+hierarchically based on platform. Each module has a number of `#[cfg]`'d
+children, but only one is ever actually compiled. Each module then reexports all
+the contents of its children.
+
+This means that for each platform that libc supports, the path from a
+leaf module to the root will contain all bindings for the platform in question.
+Consequently, this indicates where an API should be added! Adding an API at a
+particular level in the hierarchy means that it is supported on all the child
+platforms of that level. For example, when adding a Unix API it should be added
+to `src/unix/mod.rs`, but when adding a Linux-only API it should be added to
+`src/unix/notbsd/linux/mod.rs`.
+
+If you're not 100% sure at what level of the hierarchy an API should be added
+at, fear not! This crate has CI support which tests any binding against all
+platforms supported, so you'll see failures if an API is added at the wrong
+level or has different signatures across platforms.
+
+With that in mind, the steps for adding a new API are:
+
+1. Determine where in the module hierarchy your API should be added.
+2. Add the API.
+3. Send a PR to this repo.
+4. Wait for CI to pass, fixing errors.
+5. Wait for a merge!
+
+### Test before you commit
+
+We have two automated tests running on [Travis](https://travis-ci.org/rust-lang/libc):
+
+1. [`libc-test`](https://github.com/alexcrichton/ctest)
+  - `cd libc-test && cargo run`
+  - Use the `skip_*()` functions in `build.rs` if you really need a workaround.
+2. Style checker
+  - `rustc ci/style.rs && ./style src`

+The goal of the libc crate is to have CI running everywhere to have the
+strongest guarantees about the definitions that this library contains, and as a
+result the CI is pretty complicated and also pretty large! Hopefully this can
+serve as a guide through the sea of scripts in this directory and elsewhere in
+this project.
+
+# Files
+
+First up, let's talk about the files in this directory:
+
+* `run-travis.sh` - a shell script run by all Travis builders, this is
+  responsible for setting up the rest of the environment such as installing new
+  packages, downloading Rust target libraries, etc.
+
+* `run.sh` - the actual script which runs tests for a particular architecture.
+  Called from the `run-travis.sh` script this will run all tests for the target
+  specified.
+
+* `cargo-config` - Cargo configuration of linkers to use copied into place by
+  the `run-travis.sh` script before builds are run.
+
+* `dox.sh` - script called from `run-travis.sh` on only the linux 64-bit nightly
+  Travis bots to build documentation for this crate.
+
+* `landing-page-*.html` - used by `dox.sh` to generate a landing page for all
+  architectures' documentation.
+
+* `run-qemu.sh` - see discussion about QEMU below
+
+* `mips`, `rumprun` - instructions to build the docker image for each respective
+  CI target
+
+# CI Systems
+
+Currently this repository leverages a combination of Travis CI and AppVeyor for
+running tests. The triples tested are:
+
+* AppVeyor
+  * `{i686,x86_64}-pc-windows-{msvc,gnu}`
+* Travis
+  * `{i686,x86_64,mips,aarch64}-unknown-linux-gnu`
+  * `x86_64-unknown-linux-musl`
+  * `arm-unknown-linux-gnueabihf`
+  * `arm-linux-androideabi`
+  * `{i686,x86_64}-apple-{darwin,ios}`
+  * `x86_64-rumprun-netbsd`
+  * `x86_64-unknown-freebsd`
+  * `x86_64-unknown-openbsd`
+
+The Windows triples are all pretty standard, they just set up their environment
+then run tests, no need for downloading any extra target libs (we just download
+the right installer). The Intel Linux/OSX builds are similar in that we just
+download the right target libs and run tests. Note that the Intel Linux/OSX
+builds are run on stable/beta/nightly, but are the only ones that do so.
+
+The remaining architectures look like:
+
+* Android runs in a [docker image][android-docker] with an emulator, the NDK,
+  and the SDK already set up. The entire build happens within the docker image.
+* The MIPS, ARM, and AArch64 builds all use the QEMU userspace emulator to run
+  the generated binary to actually verify the tests pass.
+* The MUSL build just has to download a MUSL compiler and target libraries and
+  then otherwise runs tests normally.
+* iOS builds need an extra linker flag currently, but beyond that they're built
+  as standard as everything else.
+* The rumprun target builds an entire kernel from the test suite and then runs
+  it inside QEMU using the serial console to test whether it succeeded or
+  failed.
+* The BSD builds, currently OpenBSD and FreeBSD, use QEMU to boot up a system
+  and compile/run tests. More information on that below.
+
+[android-docker]: https://github.com/rust-lang/rust-buildbot/blob/master/slaves/android/Dockerfile
+
+## QEMU
+
+Lots of the architectures tested here use QEMU in the tests, so it's worth going
+over all the crazy capabilities QEMU has and the various flavors in which we use
+it!
+
+First up, QEMU has userspace emulation where it doesn't boot a full kernel, it
+just runs a binary from another architecture (using the `qemu-<arch>` wrappers).
+We provide it the runtime path for the dynamically loaded system libraries,
+however. This strategy is used for all Linux architectures that aren't intel.
+Note that one downside of this QEMU system is that threads are barely
+implemented, so we're careful to not spawn many threads.
+
+For the rumprun target the only output is a kernel image, so we just use that
+plus the `rumpbake` command to create a full kernel image which is then run from
+within QEMU.
+
+Finally, the fun part, the BSDs. Quite a few hoops are jumped through to get CI
+working for these platforms, but the gist of it looks like:
+
+* Cross compiling from Linux to any of the BSDs seems to be quite non-standard.
+  We may be able to get it working but it might be difficult at that point to
+  ensure that the libc definitions align with what you'd get on the BSD itself.
+  As a result, we try to do compiles within the BSD distro.
+* On Travis we can't run a VM-in-a-VM, so we resort to userspace emulation
+  (QEMU).
+* Unfortunately on Travis we also can't use KVM, so the emulation is super slow.
+
+With all that in mind, the way BSD is tested looks like:
+
+1. Download a pre-prepared image for the OS being tested.
+2. Generate the tests for the OS being tested. This involves running the `ctest`
+   library over libc to generate a Rust file and a C file which will then be
+   compiled into the final test.
+3. Generate a disk image which will later be mounted by the OS being tested.
+   This image is mostly just the libc directory, but some modifications are made
+   to compile the generated files from step 2.
+4. The kernel is booted in QEMU, and it is configured to detect the libc-test
+   image being available, run the test script, and then shut down afterwards.
+5. Look for whether the tests passed in the serial console output of the kernel.
+
+There's some pretty specific instructions for setting up each image (detailed
+below), but the main gist of this is that we must avoid a vanilla `cargo run`
+inside of the `libc-test` directory (which is what it's intended for) because
+that would compile `syntex_syntax`, a large library, with userspace emulation.
+This invariably times out on Travis, so we can't do that.
+
+Once all those hoops are jumped through, however, we can be happy that we're
+testing almost everything!
+
+Below are some details of how to set up the initial OS images which are
+downloaded. Each image must be enabled have input/output over the serial
+console, log in automatically at the serial console, detect if a second drive in
+QEMU is available, and if so mount it, run a script (it'll specifically be
+`run-qemu.sh` in this folder which is copied into the generated image talked
+about above), and then shut down.
+
+### QEMU setup - FreeBSD
+
+1. Download CD installer (most minimal is fine)
+2. `qemu-img create -f qcow2 foo.qcow2 2G`
+3. `qemu -cdrom foo.iso -drive if=virtio,file=foo.qcow2 -net nic,model=virtio -net user`
+4. run installer
+5. `echo 'console="comconsole"' >> /boot/loader.conf`
+6. `echo 'autoboot_delay="0"' >> /boot/loader.conf`
+7. look at /etc/ttys, see what getty argument is for ttyu0
+8. edit /etc/gettytab, look for ttyu0 argument, prepend `:al=root` to line
+   beneath
+
+(note that the current image has a `freebsd` user, but this isn't really
+necessary)
+
+Once that's done, arrange for this script to run at login:
+
+```
+#!/bin/sh

+### QEMU setup - OpenBSD
+
+1. Download CD installer
+2. `qemu-img create -f qcow2 foo.qcow2 2G`
+3. `qemu -cdrom foo.iso -drive if=virtio,file=foo.qcow2 -net nic,model=virtio -net user`
+4. run installer
+5. `echo 'set tty com0' >> /etc/boot.conf`
+6. `echo 'boot' >> /etc/boot.conf`
+7. Modify /etc/ttys, change the `tty00` at the end from 'unknown off' to
+   'vt220 on secure'
+8. Modify same line in /etc/ttys to have `"/root/foo.sh"` as the shell
+9. Add this script to `/root/foo.sh`
+
+```
+#!/bin/sh
+exec 1>/dev/tty00
+exec 2>&1
+
+if mount -t ext2fs /dev/sd1c /mnt; then
+  sh /mnt/run.sh /mnt
+  shutdown -ph now
+fi
+
+# limited shell...
+exec /bin/sh < /dev/tty00
+```
+
+10. `chmod +x /root/foo.sh`

+//! Simple script to verify the coding style of this library
+//!
+//! ## How to run
+//!
+//! The first argument to this script is the directory to run on, so running
+//! this script should be as simple as:
+//!
+//! ```notrust
+//! rustc ci/style.rs
+//! ./style src
+//! ```
+//!
+//! ## Guidelines
+//!
+//! The current style is:
+//!
+//! * No trailing whitespace
+//! * No tabs
+//! * 80-character lines
+//! * `extern` instead of `extern "C"`
+//! * Specific module layout:
+//!     1. use directives
+//!     2. typedefs
+//!     3. structs
+//!     4. constants
+//!     5. f! { ... } functions
+//!     6. extern functions
+//!     7. modules + pub use
+//!
+//! Things not verified:
+//!
+//! * alignment
+//! * 4-space tabs
+//! * leading colons on paths
