基于构件化操作系统的扩展的事件同步对象

在一个支持多线程的操作系统中,所有的应用程序实际上都以是线程的方式运行的。这时,就必须考虑多个线程并发访问同一个数据对象时的同步互斥问题。上海科泰世纪科技有限公司的基于CAR技术的Elastos操作系统就是一个多进程、多线程的操作系统。文中介绍的就是如何利用其扩展的事件同步对象实现线程间同步及消息交换的问题。

Extended Event Synchronization Object on Component Based Operating System

In a system which supports multi-thread,all the application programs are running in a thread-based way.Therefore,have to consider the problem of synchronization when there has the possibility that many threads accessing the same data object concurrently.The Elastos,invented by Shanghai Koretide Corporation was such a CAR technology-based operating system that supports multi-process and multi-thread,and this paper will give a presentation of how to use the extended event synchronization object to implement synchronization and message exchange among threads.
