Fwd: Acessing scheme procedures in C code

[Daniel Martins Barbosa Fortes Manoel]

I'm  currently working on a small text adventure engine using guile, and i
need to acess some procedures inside a Scheme script, is there any way to get
a pointer to a procedure inside script?

here's the problem:

class obj {
                int (*look_handle) (void);

                int install_look_handle(int(*look_handle));
}


        i wanted to define the look_handle inside the script, and call the C 
code to
install, is there any way to do this??
Thanks
