通过int pthread_setcanceltype(int type, int *oldtype) 来设置取消类型,PTHREAD_CANCEL_ASYCHRONOUS代表接收到取消请求后立即行动,THREAD_CANCEL_DEFERRED表示在接收到请求后,等待函数执行下述动作之一后才取消线程:pthread_join, pthread_cond_wait, pthread_cond_timeout, pthread_test_cancel, sem_wait, sigwait等 ...
thread first ( thread_1); // 开启线程,调用:thread_1() thread second (thread_2,100); // 开启线程,调用:thread_2(100) //thread third(thread_2,3);//开启第3个线程,共享thread_2函数。 std::cout << "主线程\n"; first.join(); //必须说明添加线程的方式 second.join(); std::cout <<...
要让一个thread在背景不断的执行,最简单的方式就是在该thread执行无穷回圈,如while(1) {},这种写法虽可行,却会让CPU飙高到100%,因为CPU一直死死的等,其实比较好的方法是,背景平时在Sleep状态,当前景呼叫背景时,背景马上被唤醒,执行该做的事,做完马上Sleep,等待前景呼叫。当背景sem_wait()时,就是马上处于Slee...
waitThread.Abort(); 1. 强制终止掉... 所以报这个异常了... 后来想对策如下几种: 1.不强制终止线程..让winform自己close()掉..然后子线程就会关闭掉.. 2.强制终止线程,,,但是捕获异常...把异常给闷掉... 先尝试了第二套方案... 异常捕获了然后也闷掉了... 结果还是出错..看样要想捕获另外一个线...
使用线程并行执行 for 循环 假设我们有一个数组,我们需要对数组中的每个元素执行一个任务。我们可以使用线程来并行执行这些任务。以下是一个示例代码: publicclassParallelForLoop{publicstaticvoidmain(String[]args){int[]array={1,2,3,4,5,6,7,8,9,10};intnumberOfThreads=4;// 创建线程数组Thread[]thread...
while (fut.wait_for(100ms) != future_status::ready) { cout // 死循环 } cout std::thread与std::async 线程与任务异同: std::thread没有直接获取返回值的方法,且如果线程中抛出异常,程序会直接崩溃(terminate); 基于线程(thread)的编程需要考虑线程耗尽、超额认购(oversubscription)、加载平衡、新平台适应...
