Lockfree Queue

Hi all, I'm reading your forums for a long time now, but this is my first post here. I'm interesting in Lockfree stack or queue and i've read the post on the lockless link list. After long research on the net I've found this code: http://mooproductions.blogspot.com/feeds/posts/default #ifndef _LOCKLESS_QUEUE_ #define _LOCKLESS_QUEUE_ //******************************************************************************* // Copyright (C) 2006 Casey Borders, Moo Productions // Contact: Casey.Borders@MooProductions.org // // This software is provided 'as-is', without any express or implied warranty. // In no event will the authors be held liable for any damages arising from // the use of this software. // // Permission is granted to anyone to use this software for any purpose, // including commercial applications, and to alter it and redistribute it // freely, subject to the following restrictions: // // * The origin of this software must not be misrepresented; you must not // claim that you wrote the original software.
