Provides a polling-based API to use gamepads/joysticks on Linux and Windows.
Pass -version=ps1_style or -version=xbox_style to pick your API style - the constants will use the names of the buttons on those controllers and attempt to emulate the other. ps1_style is compatible with more hardware and thus the default. XBox controllers work with either, though.
The docs for this file are quite weak, I suggest you view source of arsd.gamehelers for an example of how it might be used.
Returns the number of players actually connected
For Linux only, reads the latest joystick events into the change buffer, if available. It is non-blocking
