WaitForSingleObject：如何从_beginthreadex获取处理 [英] WaitForSingleObject : how to get handle from _beginthreadex

问题描述

hello guys这是我的代码

hello guys this is my code

#include "StdAfx.h"
#include <iostream>
#include <windows.h>
#include <process.h>  


unsigned int __stdcall threadproc(void* lparam)
{
    std::cout << "my thread" << std::endl;
    return 0;
}


int main()
{
    unsigned  uiThread1ID = 0;

    uintptr_t th = _beginthreadex(NULL, 0, threadproc, NULL, 0, &uiThread1ID);
     WaitForSingleObject(th, INFINITE/*optional timeout, in ms*/);
    return 0;
}

但我得到以下错误信息

错误C2664：'WaitForSingleObject'：无法将参数1从'uintptr_t'转换为'HANDLE'

error C2664: 'WaitForSingleObject' : cannot convert parameter 1 from 'uintptr_t' to 'HANDLE'

有人可以帮助我吗？

Could someone please help me ?

推荐答案

您需要将 uintptr_t 转换为 HANDLE ，将在此页面的第二个示例中更具体地演示：

You need to cast the uintptr_t to type HANDLE, this is demonstrated in the second example on this page, more specifically:

HANDLE hThread;
hThread = (HANDLE)_beginthreadex(...);

（注意：这只适用于 _beginthreadex ）
