C++ C++;std::当前类中的线程传递成员函数
我试图通过一个成员函数进行线程调用。问题是我在同一类的另一个成员函数中进行调用。我的意思是:C++ C++;std::当前类中的线程传递成员函数,c++,multithreading,C++,Multithreading,我试图通过一个成员函数进行线程调用。问题是我在同一类的另一个成员函数中进行调用。我的意思是: class A { void foo(int a); void bar() { int k = 2; thread t(&A::foo, this, k); } } 我还试图将this作为参考传递:this或std::ref(this),但没有成功。我到底犯了什么错 编辑:下面是给出错误的实际代码 class SUBTHREAD { public
class A {
void foo(int a);
void bar() {
int k = 2;
thread t(&A::foo, this, k);
}
}
我还试图将this
作为参考传递:this
或std::ref(this)
,但没有成功。我到底犯了什么错
