Nix seeks to provide friendly bindings to various *nix platform APIs (Linux, Darwin, ...). The goal is to not provide a 100% unified interface, but to unify what can be while still providing platform specific APIs.

For many system APIs, Nix provides a safe alternative to the unsafe APIs exposed by the libc crate. This is done by wrapping the libc functionality with types/abstractions that enforce legal/safe usage.

As an example of what Nix provides, examine the differences between what is exposed by libc and nix for the gethostname system call:

// libc api (unsafe, requires handling return code/errno)
pub unsafe extern fn gethostname(name: *mut c_char, len: size_t) -> c_int;

// nix api (returns a nix::Result)
pub fn gethostname(name: &mut [u8]) -> Result<()>;
