Module libc

"FFI" interfaces to libc.

Bindings are auto-generated from Rust's libc crate using tools/libc-bindgen. Common items have no #[cfg] guard; platform-specific items are guarded with appropriate #[cfg(...)] attributes.

Everything from libc::bindings is *-imported, so use e.g. libc::write rather than libc::bindings::write.
