上一篇介绍了同步事件EventWaitHandle,以及它的两个子类型AutoResetEvent和ManualResetEvent.下面接着介绍WaitHandle的另外两个子类型Mutex和Semaphore. 互斥体Mutex 互斥体Mutex也是Windows用来进行线程同步的内核对象.当两个或更多线程需要同时访问一个共享资源时,可以使用 Mutex 同步基元,它只向一个线程授予对共享资源的独占访问权. 如果一个线程获取了互斥体,则要获取该互斥体的第二个线程将被挂起,直到第一个线程释放该…

代码: # -*- coding: utf-8 -*- """ 多线程并发同步 ,使用信号量threading.Semaphore 逻辑: 多个线程,对同一个共享变量 ,加1,并且各自打印加1前.加1后的值 总结: 信号量也提供acquire方法和release方法,每当调用acquire方法的时候,如果内部计数器大于0,则将其减1, 如果内部计数器等于0,则会阻塞该线程,知道有线程调用了release方法将内部计数器更新到大于1位置 1. 个人感觉,信号量类似锁,创建2个大…
