Please!!!
No, no, the main question is, what are you going to do with that
"something"? Ok, the keys are probably Scheme strings, so you can
transform them into UTF byte-arrays which you can then feed into
functions like "printf". But in Scheme, you frequently work with lists
of things (lists themselves, or atoms) -- this is what a "data
structure" looks like. So when you say "something i can DEAL with with
c", what exactly is this DEALing you want to do? And with which
objects? some of them are Scheme wrappers around C structs. For those,
there is smob/unsmob. But for true Scheme data structures, you really
want to deal with them using Scheme code -- that is, using scm_call_X(),
as Carl already suggested.
