Subject: ruby extension problem

Hey guys,
I am writing a ruby extension in C++ that exposes a function to ruby,
and then opens a ruby interpreter that loads a file that can call the
function.

I am following the Pragmatic Programmers guide to embedding and
extending ruby. I have a function defined like this:

static VALUE Send (VALUE length, VALUE capMode, VALUE dev, VALUE pack)

then later to register it, there is this:

VALUE cTest;

void Init_Send() {
	cTest = rb_define_module("rpacket");
	rb_define_module_function(cTest, "Send", Send, 4);
}

However, when compiling, I get this error:

error C2664: 'rb_define_module_function' : cannot convert parameter 3
from 'VALUE (__cdecl *)(VALUE,VALUE,VALUE,VALUE)' to 'VALUE (__cdecl *)
(...)'

Anyone know why it's failing?
