Merge 66e0e0c5333e8182065193ff18b50d98fee86be6 on remote branch Change-Id: Iafc630d1cc8cb75f7d9fad9409dd9f32169b3558
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.
Add the following to your Cargo.toml
:
[dependencies] libc = "0.2"
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. This feature requires a nightly rustc.
deprecated: use_std
is deprecated, and is equivalent to std
.
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 |
cfg(target_vendor) | 1.33.0 |
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 GitHub Actions and Cirrus CI show the platforms in which libc
tests are run.
