indows多进程间数据共享的实现方法研究

Study on Method of Sharing Data Between Windows Processes

Win9x是一个虚拟内存系统 ,每一个进程都有自己独立的地址空间 ,进程之间不能直接通信 ,本文介绍了利用内存映射文件在进程间共享数据的方法 ,并给出了内存映射文件在VXI嵌入计算机软件开发中的应用实例。

Win9x is a virtual memory system.Every process has an independent address space and cannot communicate with other processes directly.A data sharing method between processes using memory mapping file is introduced.An example of memory mapping file used in VXI embedded computer software is analyzed.
