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...
cout << "线程1的ID:" << t1.get_id() << endl; cout << "线程2的ID:" << t2.get_id() << endl; 5.hardware_concurrency() 获得逻辑处理器储量,返回值为int型 int coreNum = thread::hardware_concurrency(); 四:使用 1.创建线程 void threadFun1() { cout << "this is thread fun1 !
}intmain(){intmvar=1;int&mvary=mvar;charmybuf[]="this is a test";//如果是隐式转换,会有可能主线程执行完还没进行转换// thread my_thread(myprint, mvar, mybuf);//第一个参数是函数名,后两个参数是函数的参数// 因此需要显式的转换,构造临时对象threadmy_thread(myprint, mvar, string(mybuf...
//类型转换构造函数,可以将int转化为AA(inta):m_i(a){std::cout<<"constructor"<<this<<", threadid = "<<std::this_thread::get_id()<<std::endl;}A(constA&a):m_i(a.m_i){std::cout<<"copy constructor"<<this<<", threadid = "<<std::this_thread::get_id()<<std::endl;}~A...
:thread::id到std::thread或native_handle的表,但实际上需要一个瓶颈,您可以控制所有std::thread的...
std::this_thread::sleep_for(std::chrono::minutes(1)); 改为 for(int i=0;i<60&&!bExit;...

void swap(thread& _Other) noexcept { // swap with _Other _STD swap(_Thr, _Other._Thr); } _NODISCARD bool joinable() const noexcept { // return true if this thread can be joined return _Thr._Id != 0; //原生的线程id不为0,表示底层的线程己经创建 ...
std::thread::id get_id() const noexcept; native_handle_type native_handle(); void join(); void detach(); void swap( thread& other ) noexcept; static unsigned int hardware_concurrency() noexcept; }; 从定义中我们可以得知: std::thread不支持拷贝语义。
C++11 之前,C++ 语言没有对并发编程提供语言级别的支持,这使得我们在编写可移植的并发程序时,存在诸多...
