Yes, this is possible. You can use "define-external" to define entry-points
into the library and implement the code in Scheme. One important point
is required though: you have to initialize the Scheme code once, so there
should be some sort of initialization function that executes "CHICKEN_run()",
before the callbacks are in place. See

http://chicken.wiki.br/Embedding

for more information. As Kon already pointed out, linking together a minimal
set of runtime code can be a bit of work, but is in general not a problem
and is solvable (just ask here on this list).
