calling define-class function from C++ source file

[Laurent Marzullo]

Hello,

Could anyone give me an example of how to call the function 
define-class from C++ once the goop module has been loaded.

// C++
scm_load_goops();
scm_apply( ??????? );

In fact I would like to write in C++ the following statment
(define-class <MyClass> ()
    (r #:init-value 0))

Could someone show me how to write this Scheme statment from
C/C++ ???

Thank you very much.
