在Dao中使用多线程

显示当前运行的进程-display current running proce-Displays the current running processes-display current running proce

此为操作系统实验:进程同步机制的模拟实现. 报告中有 程序流程图 解题思路 部分主要源码等!! 简介:进程是程序在一个数据集合上运行的过程，进程是并发执行的，也即系统中的多个进程轮流地占用处理器运行。 我们把如干个进程都能进行访问和修改地那些变量成为公共变量。由于进程是并发执行的，所以，如果对进程访问公共变量不加限制，那么就会产生“与时间有关”的错误，即进程执行后，所得到的结果与访问公共变量的时间有关。为了防止这类错误，系统必须要用同步机构来控制进程对公共变量的访问。一般说，同步机构是由若干条原语――同步原语――所组成。本实验要求学生模拟PV操作同步机构的实现，模拟进程的并发执行，了解进程并发执行时同步机构的作用。-operating system for this experiment : the process synchronization mechanism Simulation. A report flowchart Oklahoma as part of the main source! ! Description : The process is procedural in a data set on the process of operation, the process is complicated by the implementation of the system that is the number of rotation process to deal with occupation Operation. We can process of stem out for a visit and to amend those variables as public variables. As the process is complicated by the implementation, so if the right to visit public process variables without restrictions, it will have a "Time" is wrong, the implementation process, the results obtained with the public

一个用C做得存储管理，很好用的，是操作系统的实验-doing a C storage management, good use, the operating system is experimental

进程管理软件，相当好用！ 大家快来下啊 功能非常强大，-process management software, very useful! We Come under ah is very powerful,

一个很好的可以读取进程信息的VC++源代码-a good process information can read the source code of VC

使用内存映射文件在两个进程间进行通信-use memory-mapped file between the two processes communicate

依次执行一系列程序且每个程序之间执行有时间间隔。- Carries out between in turn a series of procedures also each procedure carries out has the time-gap.

线程库最新实现，在linux/unix上实现了创建用户态线程，使得开发多线程更加容易。-threads for the latest achievement in linux/unix achieved users to create state-threaded, making the development of multi-threaded easier.

进程和调度(kernel-) - 非常好的一篇有关连接和加载的文章, 取之与网, 用之与网, 与你分享!-process and Scheduling (kernel-)- a very good connections and the loading of the article, but it must and network and the network is used, to share with you!
