using goops classes from C

[Valentin Kamyshenko <val at kamysh dot materials dot kiev dot ua>]

Hello,

fdi.c in the goops distribution gives as example of defining goops
class. I wonder if there is a way to access slots from C and of
defining and calling the methods/generic functions at C level.

Also, considering the possibility to use goops classes instead of
smobs, is there a way of defining the non-standard mark function for a 
class?
