API halp

I need acess to some windows API stuff, namely SendInput. I'm looking at msdn so i know that it needs some arguments and so on, but what confuse me is the structures it requires, it requires a input structure, and that input structure requires a mouse/keyboard input structure in turn.

My experience with APIs so far is to copy pasta a code snippet and running it, so i'm somewhat confused on what to do.

Lanaguage i'm using is ruby.

halp please!

programming is basically iterlacing a shitload of copy pasta with eachother, adding some memes and changing a little in places to make it fit better.
