struct Music; [36 bytes] [+20 bytes] // Audio stream and music data pointer for streaming
```
raylib slightly abuses the ability to pass-by-value. In fact, only around 10% of its functions need to deal with data pointers. With this in mind, data structures are kept as small as possible (usually under 64 bytes), and internal pointers are used with functions that need to modify the data (usually *Load*, *Update* and *Unload* functions).
