/*
Demonstrates how to enumerate over devices.
 
Device enumaration requires a `ma_context` object which is initialized with `ma_context_init()`. Conceptually, the
context sits above a device. You can have many devices to one context.
 
If you use device enumeration, you should explicitly specify the same context you used for enumeration in the call to
`ma_device_init()` when you initialize your devices.
