一、break到不同类的同名函数

方法：在函数前面加类名以及作用域运算符
eg : break A::func //break 到类A的func函数

程序如下：

//gdb_test.cpp

#include<iostream>

class A {

public:

    void func() {

        std::cout << "A::func() is called" <<  std::endl;

    }

};

class B {

public:

    void func() {

        std::cout << "B::func() is called" <<  std::endl;

    }

};

int main(int argc,char *argv[])

{

    A a;

    B b;

    a.func();

    b.func();

    return 0;

}

调试过程如下：

[kiosk@localhost mess]$ gdb gdb_test
