我想从我的类中生成一个线程,线程在我的类中执行一个特定的方法。代码如下:
I am trying to spawn a thread from within my class and the thread executes a particular method in my class. The code looks like this:
class ThreadClass{ int myThread(int arg){ // do something } void createThread(){ thread t = thread(myThread,10); } } ;这段代码在编译时会引发一个错误:
This code on compilation throws an error saying
std::thread::thread(_Callable&&, _Args&& ...) [with _Callable = int (ThreadClass::*)(int), _Args = {int}] no known conversion for argument 1 from ‘<unresolved overloaded function type>’ to ‘int (ThreadClass::*&&)(int)’我不知道这里是什么是实际的错误。有人可以帮我解决这个问题吗?
I am not sure what is the actual bug here. Can someone help me with this?
感谢。
推荐答案问题是不能在没有对象的情况下调用成员函数。提供指向 的指针,以便使用当前对象:
The problem is that a member function can't be called without an object. Provide a pointer to this so that the current object is used:
thread t(&ThreadClass::myThread, this, 10);您可以使用任何 ThreadClass 对象,但在你的情况下,看起来这是正确的事情。
You could use an instance of any ThreadClass object, but in your case, it seems this is the right thing to do.
注意:对创建的线程的引用,以便稍后可以执行 join()。
NOTE: Remember you need a reference to the created thread so that you can do a join() later on.
