The value of this argument is passed to the thread pool through the pvWorkerParam parameter of CThreadPool::Initialize. When there are work items in the queue and worker threads available for work, a worker thread will pull an item off the queue and call the Execute method of the Worker ...

1. 继承Thread类 我们可以通过继承Thread类并重写其run()方法来创建一个新的线程。在run()方法中,可以定义当线程启动时执行的任务。 代码示例: classMyThreadextendsThread{publicvoidrun(){System.out.println("线程 "+Thread.currentThread().getName()+" 正在执行...");}}publicclassThreadDemo{publicstaticvo...

1. 线程(Thread) 多线程的意义在于一个应用程序中,有多个执行部分可以同时执行;对于比较耗时的操作(例如io,数据库操作),或者等待响应(如WCF通信)的操作,可以单独开启后台线程来执行,这样主线程就不会阻塞,可以继续往下执行;等到后台线程执行完毕,再通知主线程,然后做出对应操作!
线程的结束可以等待线程自然结束,也可以在线程函数中调用thread.exit()或thread.exit_thread()方法。 2、创建threading.Thread的子类来包装一个线程对象,如下例: 1. import threading 2. import time 3. class timer(threading.Thread):#The timer class is derived from the class threading.Thread ...
