Re: Calling a scheme procedure from C

Re: Calling a scheme procedure from C

[Mike Gran]

When you look up a Scheme function using scm_c_lookup, it doesn't return
the procedure.  It returns the variable that contains the procedure.  To 
then get the procedure, you have to dereference the variable using 
scm_variable_ref.

I would call the function this way...

int main (int argc, char *argv[])
{
    SCM func_symbol;
    SCM func;
   
    scm_init_guile();
   
    func_symbol = scm_c_lookup("write");
    func = scm_variable_ref(func_symbol);
   
    scm_call_1 (func, scm_int2num(10));

    exit(EXIT_SUCCESS);
}
