linux下进程间通信，简单的共享内存的实现（源代码），适合初学。-linux under the inter-process communication, a simple shared memory implementation (source code), suitable for beginners.

多个进程每秒钟向共享内存中写入数据，一个进程从共享内存中读数据-Multiple processes per second write data to shared memory, a process that reads the data from the shared memory
