Windows10 VS2017 C++多线程传参和等待线程结束

 #include "pch.h" #include <iostream> #include <windows.h> using namespace std; typedef struct MyData { const char* str; }MYDATA; //线程函数 DWORD WINAPI Fun(LPVOID lpParamter) { MYDATA *pmd = (MYDATA *)lpParamter; for (int i = 0; i < 10; i++) { cout << "Displaying " << pmd->str << endl; Sleep(500); } return 0; } int main() { //使用struct传递参数 MYDATA xstr; xstr.str = "你好!"; //使用GetExitCodeThread()轮询检查 //DWORD exitCode = 0; //HANDLE hThread = CreateThread(NULL, 0, Fun, &xstr, 0, NULL); //while (1) { // GetExitCodeThread(hThread, &exitCode); // 严重浪费 CPU 时间 // if (STILL_ACTIVE != exitCode) // break; //} //CloseHandle(hThread); //WaitForSingleObject()，cpu使用率极低 HANDLE hThread = CreateThread(NULL, 0, Fun, &xstr, 0, NULL); WaitForSingleObject(hThread, INFINITE); // 等待，直到线程被激发 CloseHandle(hThread); cout << "Child thread is over." << endl; return 0; }
