Hi guys, first time using the mailing list, hope im not doing anything wrongt :)
ok ive got some questions about the ruby core

1. C-Methods: how is it possible to do a printf command for the delivered VALUE parameters?

Example
VALUE
rb_funcall(VALUE recv, ID mid, int n, ...)
{
  ...
}
/*
  for example I would like to get the value of the variable recv printed on the command line using something like printf(recv); 
  reason for that is, that is just want to see what values any variable of the datatype VALUE has got

  I know that c types can be "easily" printed, like the type ID : printf("%s", rb_id2name(nameOfVariableID))
*/



2. C-Method: how can I get to know the datatype of a VALUE variable?

Example

VALUE
rb_somemethod(VALUE somevalue, VALUE anothervalue)
{
  char s = TYPE(somevalue); /* imagined code */
  printf("%s",s); /* imagined code */
}


3. C-Method: how can I call a method which is defined somewhere by using C ?

Example
# Rubycode
class RubyClass
  def x()
    p "x"
  end
end

/*C-code*/
void
rb_call_a_func()
{
  /*imagined code*/
  getClass("RubyClass").getMethod("x").execute();
}  


Thanks for your help, and sorry if I posted it in the wrong "section"
