You can entirely do this in Scheme.

If you want to implement an extension that has some parts to be
written in C, you can do like this

 (load-extension "libsystray" "init_systray")

or like this

(define libc-obj (dynamic-link "libc.so"))
(dynamic-args-call 'rand libc-obj '())
(dynamic-unlink libc-obj)

Happy Hacking,
