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 defaultlibclinks to the standard library. Disable this
feature remove this dependency and be able to uselibcin#![no_std]
crates. -
extra_traits: allstructs implemented inlibcareCopyandClone.
This feature derivesDebug,Eq,Hash, andPartialEq. -
const-extern-fn: Changes someextern fns intoconst extern fns.
This features requires a nightly rustc -
deprecated:
use_stdis 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 Azure and Cirrus CI show the
platforms in which libc tests are run.
