线程内的无限循环不工作[重复]

Question

正在学习一些关于多线程的教程，并编写了一些代码来创建一个无限线程。然而，无限循环似乎不起作用。循环内的打印例程只运行一次。找到下面的代码以供参考。不明白我做错了什么。我正在使用MSVC编译器。

#include <Windows.h>
#include <iostream>


DWORD __stdcall ThreadProc(LPVOID lpParameter) {

    const char* StringToPrint = (const char*)lpParameter;

    //expected this block to run infinitely.
    while (1) {
        std::cout << StringToPrint << "\n";
        Sleep(1000);
    }

    return 0;
}


int main() {

    DWORD ThreadId = 0;
    const char *Param = "Inside Thread";
    LPVOID Param1 = (LPVOID)Param;


    HANDLE Threadhandle = CreateThread(0, 0, ThreadProc, Param1, 0, &ThreadId);
    std::cout << "Thread ID " << ThreadId << " started" << "\n";
    CloseHandle(Threadhandle);
    return 0;

}

循环似乎只运行一次，因为程序在启动线程后立即终止。

如果希望线程永远运行，请在主函数中等待它完成：

    HANDLE Threadhandle = CreateThread(0, 0, ThreadProc, Param1, 0, &ThreadId);
    std::cout << "Thread ID " << ThreadId << " started" << "\n";
    WaitForSingleObject(Threadhandle, INFINITE);
    CloseHandle(Threadhandle);                    // it will never reach this
