Subject: Re: Calling C functions from Embedded Ruby Interpreter

Hello Again,

I found that the example on this page:
http://blade.nagaokaut.ac.jp/cgi-bin/scat.rb/ruby/ruby-talk/155482

does have the necessary to help me connect the dots.  I was staring at 
the example for quite a while before I sent the email out, but I guess I 
just didn't see it.

Thanks anyway.

Cheers,
Mohit.
