About Effo NetMsg Project

This is the Effo NetMsg project which provides network communication and messaging add-ons for the Effo Project or other C/C++ design and development, and develops applications and utilities such as message bus, etc. Please visit Effo Project (e.g., Google "Effo Project") to learn more.
As mentioned Effo NetMsg is a framework, exactly it's a sub-framework of the Effo Framework.
The Effo NetMsg software and source code are under the terms of MIT licnese, see Effo NetMsg License for the details.

High performance Effo Messaging uses Highly-concurrent Programming Model. Effo Messaging uses Effo Lock-free Queue and Ring Buffer, plus epoll I/O as the basic facilities. It had been well tested on both uniprocessor and mulit-core/multiprocessor Linux 2.6 (e.g. FC8/FC9) 32/64-bit systems. Please refer to Effo Core for Effo Lock-free details.

Stable Code Baseline

Source code on SVN::trunk will be updated day-to-day, so if you need newest code, please get it from SVN::trunk, and maybe it cannot be compiled or has big bugs.
While stable code will be tagged onto SVN::tags from the SVN::trunk after testing.
When building up together with the code from other Effo member project(s) (e.g. Effo Core), you'd better refer to the Effo Code Baseline, so please read the baseline ID put on SVN::trunk/code_baseline.
Whenever a new developer join the project, we'll make a source branch for the new member on SVN::branches. The reviewed code will be commited onto the SVN::trunk.
For some special versions of the source code we'd also make the branches on SVN::branches.
Please pay attention to the Effo Code Baseline to make the life easy.
