Beginner's question: I'm creating a large C array using ALLOC_N and I want to pass that pointer to different C extensions. I don't want to create a Ruby array (i.e. using rb_ary_new4()) because I won't operate on that array with any pure Ruby methods and I don't want the memcpy overhead. How can I assign a variable to that pointer in Ruby and how do I prevent any garbage collection of my array?

http://www.whytheluckystiff.net/ruby/pickaxe/html/... This explains how to use Data_Wrap_Struct and how to manage garbage collection. The issue is not so much preventing garbage collection as making it possible.
