求助,为什么已经终止了线程。线程里的函数还运行。
而且m_bFileReceivingThread 已将设置为false了
但回调函数中的循环,还在运行
加sleep(1000);也不可以
waiforsingobject等待也不可以。求高手。谢谢

很仔细地看了代码,但是没看出什么… while(false)只是跳出了当前循环,并不代表线程已经结束了。

我在Close函数中也用terminateThread终止了线程,我调试了,当close函数运行完,

直接走到listenThread函数中while循环中的accept函数,前面通过判断false退出循环,根本不运行,

而且我已经释放了端口,所以accept函数就错了。我就想解决,当close函数运行完毕,while循环直接结束

不走accept函数。有什么好方法解决吗??谢谢大神。

你需要的只是对accept函数做个异常处理
