Author: hselasky Date: Thu Oct 8 07:50:50 2015 New Revision: 289018 URL: https://svnweb.freebsd.org/changeset/base/289018 Log: MFC r284915: Make the system queue header file fully usable within C++ programs by adding macros to define class lists. This change is backwards compatible for all use within C and C++ programs. Only C++ programs will have added support to use the queue macros within classes. Previously the queue macros could only be used within structures. The queue.3 manual page has been updated to describe the new functionality and some alphabetic sorting has been done while at it.
