Hi!

Apologies for the late reply!

This is possible through UXL right now but there is no documentation online on these features. We’re working on it!

As a teaser, for example, you can write inline C code in Uno code:

```auto
extern<int>(a, b) "sum($0, $1)";

```

I’ve gone ahead and fixed up our internal handbook for using UXL, and published that with the official docs here: [https://www.fusetools.com/developers/guides/uxl-handbook](https://www.fusetools.com/developers/guides/uxl-handbook)

Note that this documentation should be considered preliminary, but should be complete enough for you to dig through should you need to use these features 🙂

I will create a library using C. then the output file is .so file.

Can i use this .so file in my fuse app?
