How to use a scheme function with C...

[Ariel Rios <jarios@usa.net>]

I'd been using Guile for a while but only in scheme-only projects. Right
I need to create a C program that at run-time may be able to use the
guile interpreter and call a specific scheme function.

For example let's suppose I want to create a C programe that receives a
value and then call the function factorial declared in Scheme.

"void main(){
int a;
name_of_function (a){ ;;this function should start the guile interpreter
and evaluate
(define (factorial n)....  ;;the function factorial.
.....
..... } }

As far as I remember that was possible using some guile functions.
However, I lost the documentation I had from Guile and cannot fing it
again.
