RCF is a portable C++ interprocess communication framework, using native C++ features to provide a new and simplified approach to writing distributed C++ software. RCF builds on the time honored concept of using interface declarations to specify remotely available functionality. Over the years there have been a number of well-known efforts building on that concept, from the venerable stalwarts of CORBA and DCOM, to modern day sequels such as Java RMI, .NET Remoting, WCF, WS-*, and so on. These frameworks all share a fundamental flaw, though: they use interfaces as a veneer for what is fundamentally an object-oriented view of distributed systems. RCF imposes no object model at all on remote interactions, and represents an interface-oriented view of distributed systems. RCF interfaces and data contracts are defined in standard C++ code, and not locked down to an elaborate object model. As such, RCF provides a simpler and more coherent programming model, than the aforementioned approaches. The RCF User Guide is intended as a guide in using RCF to write real-world distributed C++ software. Network programming is a notoriously difficult subject, but this guide will demonstrate how RCF lets you quickly and reliably construct robust, real-world networked applications.

使用shm+sem+Signal实现多进程文本通信，一个进程运行多个副本，输入命令互发消息，利用了共享内存，System V信号量加Signal

本控件与cmd控制台和其他命令行程序交互的ocx控件，效果很像Winsock或MSCOMCTL。TestForm是测试该控件用的窗体。在VB6/IE10(asp-VBS)/Excel2003下测试成功。完美兼容单换行符(chr10)和vbcrlf两种换行格式。本控件接收回显的事件为DataArrive，发送命令的方法为DataSend，使用前需先调用InitFirst方法初始化。作者雨水rainydew@qq.com，谢绝转载

linux下C语言编程4-使用共享内存实现进程间通信

进程间通信之消息队列 ( message queue ） 消息队列是消息的链表,具有特定的格式,并由消息队列标识符标识. 七种进程间通信方式： 一.无名管道（ pipe ） 二.有名管道（ fifo ） 三.共享内存 ( shared memory ) 四.信号 ( sinal ) 五.消息队列 ( message queue ） 六.信号量 ( semophore ) 七.套接字 ( socket ) 以上七种进程间通信的完整代码，皆可以在我的资源列表中获取下载： 资源列表：http://download.csdn.net/user/qiulanzhu

共享内存方式实现进程间通信。详细看我的博客：http://blog.csdn.net/pengguokan/article/details/8921346

这个文档是基于有名管道进程间通信的一些实验，可以从本质上理解进程间通信的有名管道的机理。并附有源码，可以自己复制下来，进行调试。
