资源中包含了Linux进程间通信的例子，同时有源文件和可执行文件。

源码主要包含了Linux下IPC机制的本地进程通信方式，包含了IPC共享内存，IPC信号量，IPC消息队列的实现，以及Linux下判断进程退出原因的示例程序。因为是做毕设学习时的练习程序，因此程序有详细的注释。（注意，每种通信方式需要在同时两个终端中查看验证，才可以看出效果,注意查看源码注释）-the source code included in the copressed package shows how IPC works in Linux ystem .Both source code and executable files are included.The source code was written by me as homework While I was working on my graduation project. And there was plenty of annotations in programs,so it s suitable for learning unix/linux system programing.(Attention:communications between processes are supposed to be observed in more than one terminals ,take care of that and the usage of the sooure code...)
