在写多线程时,因为某些需求,需要获得 std::this_thread::get_id() 的 std::thread::id 类型值转换为 unsigned int 类型值,并且与cout<<std::this_thread::get_id() 输出值一致 https://stackoverflow.com/questions/7432100/how-to-get-integer-thread-id-in-c11# 在stackoverflow 参考了很多方法后尝试都...
要将std::thread::id 转换为字符串,可以按照以下步骤进行: 获取std::thread::id 对象: 通常,你可以通过 std::this_thread::get_id() 获取当前线程的 std::thread::id,或者通过某个线程的 get_id() 方法来获取其 std::thread::id。 将std::thread::id 对象转换为可打印的格式: std::thread::id 没...

当前线程的 id。 示例运行此代码 #include <chrono> #include <iostream> #include <syncstream> #include <thread> using namespace std::chrono_literals; void foo() { std::thread::id this_id = std::this_thread::get_id(); std::osyncstream(std::cout) << "线程 " << this_id << " ...
std::thread 的入口函数中传递类对象时,本质上也是传递的类对象的拷贝。 #include "thread" #include "iostream" using namespace std; class demoClass { public: demoClass(int var) :m_var(var) { cout << "构造函数执行,线程id:" << this_thread::get_id() << endl; ...
