As Stephen has pointed out, just use the C function
scm_program_arguments for this.

But in case you are wondering how to call Scheme functions in general:

    SCM
    call_named_function_with_no_args (const char *name)
    {
      return scm_call_0 (scm_variable_ref (scm_c_lookup (name)));
    }

    SCM
    call_named_function_with_one_arg (const char *name, SCM arg1)
    {
      return scm_call_1 (scm_variable_ref (scm_c_lookup (name)), arg1);
    }

But if you want to call a function more than once, you should of
course store away the result of scm_variable_ref and use it directly
with scm_call_<n>.

The function scm_c_call_with_current_module is used to temporarily
switch to a different module and execute code there.  It is not
related to calling Scheme functions.

(scm_call_<n> is unfortunately not yet in the 1.6.x manual...)
