GDB调试之多线程调试管理(十四)

一、线程管理相关命令的介绍

info threads：查看所有线程信息
thread find：查找线程
thread num：切换线程
thread name：设置线程名字
b breakpoint thread id：为线程设置断点
thread apply：为线程执行命令
set scheduler-locking off|on|step：锁定线程

调试代码示例：

#include <iostream>
#include <cstring>
#include <thread>
using namespace std;
class test
{
public:
    test(){}
    virtual ~test(){}
public:
    static void do_work_1()
    {
        cout << "do work 1" << endl;
        std::this_thread::sleep_for(std::chrono::seconds(2));
        cout << "thread do work 1 exited" << endl;
    }
    void do_work_2()
    {
        cout << "do work 2" << endl;
        std::this_thread::sleep_for(std::chrono::seconds(2));
        cout << "thread do work 2 exited" << endl;
    }
    void do_work_3(void *arg,int x,int y)
    {
        char *data = (char*)arg;
        cout << "do work 3:" << data << ",x=" << x << ",y=" << y << endl;
        std::this_thread::sleep_for(std::chrono::seconds(2));
        cout << "thread do work 3 exited" << endl;
    }
};
void test_thread(void *data)
{
    int *val = (int*)data;
    cout << "thread data:" << *val << endl;
    std::this_thread::sleep_for(std::chrono::seconds(2));
    cout << "test thread exited" << endl;
}
int main(int argc,char** argv)
{
    int data=10;
    thread t1(&test_thread,(void*)&data);
 
    thread t2(&test::do_work_1);    
     
    test test3;
    thread t3(&test::do_work_2,test3);
     
    test test4;
    thread t4(&test::do_work_3,test4,(void*)"test",10,20);
     
    test test5;
    thread t5(&test::do_work_3,test5,(void*)"test2",30,40);
 
    t1.join();
    t2.join();
    t3.join();
    t4.join();
    t5.join();
    cout << "threads exit" << endl;
    return 0;
}
