Subject: Newbie Ruby and C question

I'm trying to write an interface to the Ruby regular expressions engine 
using a C dll, but I'm neither a Ruby nor C wiz. Can someone tell me 
what's wrong with the following:

#include <ruby.h>
#include <windows.h>

typedef struct RRegexp RegExp;

int regExMatch(int pos, char *pattern, char *text)
{
    RegExp *re = RREGEXP(rb_reg_new(pattern, 0, 1));
    result = rb_funcall(re, rb_intern("match"), 1, *text);
    // re will be a Ruby nil if no match is found.
    return RTEST(result);
}

I get a GPF on the first line of regExMatch.

I just need a C method equivalent of Regexp.match that I can export in a 
dll. Is this even the best way to go about such a thing or is there 
something better?
