中断线程提振 [英] Interrupting boost thread

问题描述

我希望能够中断一个线程，如下。

I would like to be able to interrupt a thread as follows.

void mainThread(char* cmd)
{   
    if (!strcmp(cmd, "start"))
        boost::thread thrd(sender); //start thread

    if (!strcmp(cmd, "stop"))
        thrd.interrupt();       // doesn't work, because thrd is undefined here

}

thrd.interrupt（）是不可能的，因为 THRD 的对象是不确定的，当我试图打断它。我该如何解决这个问题？

thrd.interrupt() is not possible because thrd object is undefined when I try to interrupt it. How can I fix this?

推荐答案

使用的<一个href=\"http://www.boost.org/doc/libs/1_47_0/doc/html/thread/thread_management.html#thread.thread_management.thread.move_assignment\"相对=nofollow>移动赋值操作符：

void mainThread(char* cmd)
{   
    boost::thread thrd;

    if (!strcmp(cmd, "start"))
        thrd = boost::thread(sender); //start thread

    if (!strcmp(cmd, "stop"))
        thrd.interrupt();

}
