This crate provides convenience methods for encoding and decoding numbers in
either big-endian or little-endian order. This is meant to replace the old
methods defined on the standard library `Reader` and `Writer` traits.
[![Build status](https://api.travis-ci.org/BurntSushi/byteorder.png)](https://travis-ci.org/BurntSushi/byteorder)
[![](http://meritbadge.herokuapp.com/byteorder)](https://crates.io/crates/byteorder)
Dual-licensed under MIT or the [UNLICENSE](http://unlicense.org).
### Documentation
[http://burntsushi.net/rustdoc/byteorder/](http://burntsushi.net/rustdoc/byteorder/).
The documentation includes examples.
### Installation
This crate works with Cargo and is on
[crates.io](https://crates.io/crates/byteorder). The package is regularly
updated. Add it to your `Cargo.toml` like so:
```toml
[dependencies]
byteorder = "0.5"
```
If you want to augment existing `Read` and `Write` traits, then import the
extension methods like so:
```rust
extern crate byteorder;
use byteorder::{ReadBytesExt, WriteBytesExt, BigEndian, LittleEndian};
```
For example:
```rust
use std::io::Cursor;
use byteorder::{BigEndian, ReadBytesExt};
let mut rdr = Cursor::new(vec![2, 5, 3, 0]);
// Note that we use type parameters to indicate which kind of byte order
// we want!
assert_eq!(517, rdr.read_u16::<BigEndian>().unwrap());
assert_eq!(768, rdr.read_u16::<BigEndian>().unwrap());
```
### `no_std` crates
This crate has a feature, `std`, that is enabled by default. To use this crate
in a `no_std` context, add the following to your `Cargo.toml`:
```toml
[dependencies]
byteorder = { version = "0.5", default-features = false }
```

/*!
This crate provides convenience methods for encoding and decoding numbers
in either big-endian or little-endian order.
The organization of the crate is pretty simple. A trait, `ByteOrder`, specifies
byte conversion methods for each type of number in Rust (sans numbers that have
a platform dependent size like `usize` and `isize`). Two types, `BigEndian`
and `LittleEndian` implement these methods. Finally, `ReadBytesExt` and
`WriteBytesExt` provide convenience methods available to all types that
implement `Read` and `Write`.
# Examples
Read unsigned 16 bit big-endian integers from a `Read` type:
```rust
use std::io::Cursor;
use byteorder::{BigEndian, ReadBytesExt};
let mut rdr = Cursor::new(vec![2, 5, 3, 0]);
// Note that we use type parameters to indicate which kind of byte order
// we want!
assert_eq!(517, rdr.read_u16::<BigEndian>().unwrap());
assert_eq!(768, rdr.read_u16::<BigEndian>().unwrap());
```
Write unsigned 16 bit little-endian integers to a `Write` type:
```rust
use byteorder::{LittleEndian, WriteBytesExt};
let mut wtr = vec![];
wtr.write_u16::<LittleEndian>(517).unwrap();
wtr.write_u16::<LittleEndian>(768).unwrap();
assert_eq!(wtr, vec![5, 2, 0, 3]);
```

/// ByteOrder describes types that can serialize integers as bytes.

# gcc-rs
A library to compile C/C++ code into a Rust library/application.
[![Build Status](https://travis-ci.org/alexcrichton/gcc-rs.svg?branch=master)](https://travis-ci.org/alexcrichton/gcc-rs)
[![Build status](https://ci.appveyor.com/api/projects/status/onu270iw98h81nwv?svg=true)](https://ci.appveyor.com/project/alexcrichton/gcc-rs)
[Documentation](http://alexcrichton.com/gcc-rs)
A simple library meant to be used as a build dependency with Cargo packages in
order to build a set of C/C++ files into a static archive. Note that while this
crate is called "gcc", it actually calls out to the most relevant compile for
a platform, for example using `cl` on MSVC. That is, this crate does indeed work
on MSVC!
## Using gcc-rs
First, you'll want to both add a build script for your crate (`build.rs`) and
also add this crate to your `Cargo.toml` via:
```toml
[package]
# ...
build = "build.rs"
[build-dependencies]
gcc = "0.3"
```
Next up, you'll want to write a build script like so:
```rust,no_run
// build.rs
extern crate gcc;
fn main() {
gcc::compile_library("libfoo.a", &["foo.c", "bar.c"]);
}
```
And that's it! Running `cargo build` should take care of the rest and your Rust
application will now have the C files `foo.c` and `bar.c` compiled into it. You
can call the functions in Rust by declaring functions in your Rust code like so:
```
extern {
fn foo_function();
fn bar_function();
}
pub fn call() {
unsafe {
foo_function();
bar_function();
}
}
fn main() {
// ...
}
```
## External configuration via environment variables
To control the programs and flags used for building, the builder can set a
number of different environment variables.
* `CFLAGS` - a series of space separated flags passed to "gcc". Note that
individual flags cannot currently contain spaces, so doing
something like: "-L=foo\ bar" is not possible.
* `CC` - the actual C compiler used. Note that this is used as an exact
executable name, so (for example) no extra flags can be passed inside
this variable, and the builder must ensure that there aren't any
trailing spaces. This compiler must understand the `-c` flag. For
certain `TARGET`s, it also is assumed to know about other flags (most
common is `-fPIC`).
* `AR` - the `ar` (archiver) executable to use to build the static library.
Each of these variables can also be supplied with certain prefixes and suffixes,
in the following prioritized order:
1. `<var>_<target>` - for example, `CC_x86_64-unknown-linux-gnu`
2. `<var>_<target_with_underscores>` - for example, `CC_x86_64_unknown_linux_gnu`
3. `<build-kind>_<var>` - for example, `HOST_CC` or `TARGET_CFLAGS`
4. `<var>` - a plain `CC`, `AR` as above.
If none of these variables exist, gcc-rs uses built-in defaults
In addition to the the above optional environment variables, `gcc-rs` has some
functions with hard requirements on some variables supplied by [cargo's
build-script driver][cargo] that it has the `TARGET`, `OUT_DIR`, `OPT_LEVEL`,
and `HOST` variables.
[cargo]: http://doc.crates.io/build-script.html#inputs-to-the-build-script
## Optional features
Currently gcc-rs supports parallel compilation (think `make -jN`) but this
feature is turned off by default. To enable gcc-rs to compile C/C++ in parallel,
you can change your dependency to:
```toml
[build-dependencies]
gcc = { version = "0.3", features = ["parallel"] }
```
By default gcc-rs will limit parallelism to `$NUM_JOBS`, or if not present it
will limit it to the number of cpus on the machine.
## Compile-time Requirements
To work properly this crate needs access to a C compiler when the build script
is being run. This crate does not ship a C compiler with it. The compiler
required varies per platform, but there are three broad categories:
* Unix platforms require `cc` to be the C compiler. This can be found by
installing gcc/clang on Linux distributions and Xcode on OSX, for example.
* Windows platforms targeting MSVC (e.g. your target triple ends in `-msvc`)
require `cl.exe` to be available and in `PATH`. This is typically found in
standard Visual Studio installations and the `PATH` can be set up by running
the appropriate developer tools shell.
* Windows platforms targeting MinGW (e.g. your target triple ends in `-gnu`)
require `gcc` to be available in `PATH`. We recommend the
[MinGW-w64](http://mingw-w64.org) distribution, which is using the
[Win-builds](http://win-builds.org) installation system.
You may also acquire it via
[MSYS2](http://msys2.github.io), as explained [here][msys2-help]. Make sure
to install the appropriate architecture corresponding to your installation of
rustc. GCC from older [MinGW](http://www.mingw.org) project is compatible
only with 32-bit rust compiler.
[msys2-help]: http://github.com/rust-lang/rust#building-on-windows
## C++ support
`gcc-rs` supports C++ libraries compilation by using the `cpp` method on
`Config`:
```rust,no_run
extern crate gcc;
fn main() {
gcc::Config::new()
.cpp(true) // Switch to C++ library compilation.
.file("foo.cpp")
.compile("libfoo.a");
}
```
When using C++ library compilation switch, the `CXX` and `CXXFLAGS` env
variables are used instead of `CC` and `CFLAGS` and the C++ standard library is
linked to the crate target.
## License
`gcc-rs` is primarily distributed under the terms of both the MIT license and
the Apache License (Version 2.0), with portions covered by various BSD-like
licenses.
See LICENSE-APACHE, and LICENSE-MIT for details.

//! Use the default configuration:
//!
//! ```no_run
//! extern crate gcc;
//!
//! fn main() {
//! gcc::compile_library("libfoo.a", &["src/foo.c"]);

//! Quoting from [UTS #46’s introduction](http://www.unicode.org/reports/tr46/#Introduction):
//!
//! > Initially, domain names were restricted to ASCII characters.
//! > A system was introduced in 2003 for internationalized domain names (IDN).
//! > This system is called Internationalizing Domain Names for Applications,
//! > or IDNA2003 for short.
//! > This mechanism supports IDNs by means of a client software transformation
//! > into a format known as Punycode.
//! > A revision of IDNA was approved in 2010 (IDNA2008).
//! > This revision has a number of incompatibilities with IDNA2003.
//! >
//! > The incompatibilities force implementers of client software,
//! > such as browsers and emailers,
//! > to face difficult choices during the transition period
//! > as registries shift from IDNA2003 to IDNA2008.
//! > This document specifies a mechanism
//! > that minimizes the impact of this transition for client software,
//! > allowing client software to access domains that are valid under either system.

copyright notice that is included in or attached to the work
(an example is provided in the Appendix below).
"Derivative Works" shall mean any work, whether in Source or Object
form, that is based on (or derived from) the Work and for which the
editorial revisions, annotations, elaborations, or other modifications

separable from, or merely link (or bind by name) to the interfaces of,
the Work and Derivative Works thereof.
"Contribution" shall mean any work of authorship, including
the original version of the Work and any modifications or additions
to that Work or Derivative Works thereof, that is intentionally
submitted to Licensor for inclusion in the Work by the copyright owner

3. Grant of Patent License. Subject to the terms and conditions of
this License, each Contributor hereby grants to You a perpetual,
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
(except as stated in this section) patent license to make, have made,
use, offer to sell, sell, import, and otherwise transfer the Work,
where such license applies only to those patent claims licensable
by such Contributor that are necessarily infringed by their
Contribution(s) alone or by combination of their Contribution(s)
with the Work to which such Contribution(s) was submitted. If You
institute patent litigation against any entity (including a
cross-claim or counterclaim in a lawsuit) alleging that the Work
or a Contribution incorporated within the Work constitutes direct
or contributory patent infringement, then any patent licenses
granted to You under this License for that Work shall terminate
as of the date such litigation is filed.
4. Redistribution. You may reproduce and distribute copies of the
Work or Derivative Works thereof in any medium, with or without
modifications, and in Source or Object form, provided that You
meet the following conditions:
(a) You must give any other recipients of the Work or
Derivative Works a copy of this License; and
(b) You must cause any modified files to carry prominent notices
stating that You changed the files; and

that You distribute, all copyright, patent, trademark, and
attribution notices from the Source form of the Work,
excluding those notices that do not pertain to any part of
the Derivative Works; and
(d) If the Work includes a "NOTICE" text file as part of its
distribution, then any Derivative Works that You distribute must

within such NOTICE file, excluding those notices that do not
pertain to any part of the Derivative Works, in at least one
of the following places: within a NOTICE text file distributed
as part of the Derivative Works; within the Source form or
documentation, if provided along with the Derivative Works; or,
within a display generated by the Derivative Works, if and
wherever such third-party notices normally appear. The contents
of the NOTICE file are for informational purposes only and
do not modify the License. You may add Your own attribution
notices within Derivative Works that You distribute, alongside
or as an addendum to the NOTICE text from the Work, provided
that such additional attribution notices cannot be construed
as modifying the License.
You may add Your own copyright statement to Your modifications and
may provide additional or different license terms and conditions
for use, reproduction, or distribution of Your modifications, or
for any such Derivative Works as a whole, provided Your use,
reproduction, and distribution of the Work otherwise complies with
the conditions stated in this License.
5. Submission of Contributions. Unless You explicitly state otherwise,
any Contribution intentionally submitted for inclusion in the Work
by You to the Licensor shall be under the terms and conditions of
this License, without any additional terms or conditions.
Notwithstanding the above, nothing herein shall supersede or modify

WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
implied, including, without limitation, any warranties or conditions

whether in tort (including negligence), contract, or otherwise,
unless required by applicable law (such as deliberate and grossly
negligent acts) or agreed to in writing, shall any Contributor be
liable to You for damages, including any direct, indirect, special,
incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.
9. Accepting Warranty or Additional Liability. While redistributing
the Work or Derivative Works thereof, You may choose to offer,
and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
License. However, in accepting such obligations, You may act only
on Your own behalf and on Your sole responsibility, not on behalf
of any other Contributor, and only if You agree to indemnify,
defend, and hold each Contributor harmless for any liability
incurred by, or claims asserted against, such Contributor by reason
of your accepting any such warranty or additional liability.

```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.

## 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
sudo kldload ext2fs
[ -e /dev/vtbd1 ] || exit 0
sudo mount -t ext2fs /dev/vtbd1 /mnt
sh /mnt/run.sh /mnt
sudo poweroff
```

### 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`
