General maintenance to make the examples run again.

[somethingelseentirely]

Hey,

I wanted to use these bindings for a project of mine, so I figured I'd polish them up a bit.

I've made changed to have them run on macOS, fixed some typos, and tried to improve the error handling and reporting situation a bit.

Thoughts and suggestions more than welcome! I'm fairly new to Zig :)

Cheers!
