Common lisp gray threads

Question

Is there a tutorial on using gray streams?

I want to create a class that reads from a file, looking for a specific set of bytes. My initial thought was to use gray streams, but could not find any source information.

Answer 1

I found this helpful. In SBCL, gray streams are in the package :GRAY .

Answer 2

Perhaps the examples from the SBCL guide can help you get started?
