Identification of VALUE recv

hey
how is it possible to get the value(s) of the variable receiver in rb_funcall?

Function:
VALUE
rb_funcall(VALUE recv, ID mid, int n, ...)

is there something like: StringValueCStr(recv) ?

the thing is, I want to know if a function x was called by rb_funcall. therefor I want to see if the value of the revc is something like "x"

Further example:

class X
    def hi()
      p "hello"
    end
end
ix = X.new
ix.hi # rb_funcall is invoked

so the recv shall be hi() , which should be the value of recv or??

thank you

no, recv is the VALUE for ix. mid is the id for :hi, n will be 0. It would be roughly equivalent to :

  rb_funcall(ix, rb_intern("hi"), 0);

What I _think_ you're asking is "what is the name of the reciever for this rb_funcall" and there isn't one.
