This commits adds a second FreeBSD 12 build job, and splits the implementation of the FreeBSD module into two modules, one for FreeBSD 11, and one for FreeBSD 12. The FreeBSD 11 module is compiled always by default, and is mostly forward compatible with FreeBSD 12 systems. The FreeBSD 12 module is only built for now in libc's CI, and uses FreeBSD 12 data types and APIs, linking to symbols that are only available in FreeBSD 12. Basically, when LIBC_CI env variable is defined, and the host system is a FreeBSD 12 system, then the FreeBSD 12 module is automatically built and tested. Conditional compilation is done using a `cfg(freebsd12)` flag. This commit also re-enables many tests, and documents why some remain disabled. |

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
-
std
: by defaultlibc

. -
deprecated:
use_std
is deprecated, and is equivalent tostd
.
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.
