This module lets you inspect the value of errno, the magic thread-local value that glibc and other libraries use to signal errors.

You probably don't need it unless you're dealing with C functions directly, for example because you're writing Rust bindings to an existing C library.

how to build

rustc --lib

how to use

use errno;
use std;

import strerror = errno::strerror;
import errno = errno::errno;

fn main() {
  std::io::println(strerror(errno())); // prints "No such file or directory"

known bugs

Currently only works on Linux. Requires glibc 2.3.4 or better. Support for OS X and Solaris may be added in the future.
