What is the best and shortest way to create a WatchDogTimer class, which can wait some time and then died? 创建WatchDogTimer类的最佳和最短方法是什么,它可以等待一段时间然后死掉?
So when I'm doing something like 所以当我做类似的事情时
WatchDogTimer wdt (10);
wdt
will be available only in next 10 seconds. wdt
仅在接下来的10秒内可用。
How can I do this? 我怎样才能做到这一点?
ps: yeah, I saw that thread, but it did not actually help. ps:是的,我看到了那个线程,但实际上并没有帮助。
Create an object on the heap with new
and hand it to a shared_ptr
. 使用
new
在堆上创建一个对象,并将其传递给shared_ptr
。 Then hold that shared pointer only from a thread that sleeps for 10 seconds before exiting. 然后仅在退出前休眠10秒的线程中持有该共享指针。 Make sure the thread is the only instance of
shared_ptr
and all other references are weak_ptr
s. 确保该线程是
shared_ptr
的唯一实例,而所有其他引用均为weak_ptr
。 After the 10 seconds weak_ptr::get()
will return null. 10秒钟后,
weak_ptr::get()
将返回null。
