Latest on Hackage:0.1

This package is not currently in any snapshots. If you're interested in using it, we recommend adding it to Stackage Nightly. Doing so will make builds more reliable, and allow stackage.org to host generated Haddocks.

errno is a small utility to supplement the FFI.

I found this in some cases useful for when I wanted to handle errors from both C & Haskell on equal footing.
