[問題] _beginthread 後，使用 CloseHandle 出現錯誤

[rosemary0401 (rosemary0401)]

仿照網路上找到的範例，練習寫thread

程式碼如下：

#include <iostream>
#include <windows.h>
#include <process.h>
#define THREAD_COUNT 2

using namespace std;

int g_num = 0;

void ThreadVariable1(void* argu)
{
        Sleep(3000);
        g_num = 100;
        _endthread();
}

void ThreadVariable2(void* argu)
{
        Sleep(3000);
        g_num = 50;
        _endthread();
}

void main()
{
        HANDLE threadArray[THREAD_COUNT];

        threadArray[0] = (HANDLE) _beginthread(ThreadVariable1, 0, NULL);
        threadArray[1] = (HANDLE) _beginthread(ThreadVariable2, 0, NULL);

        WaitForMultipleObjects(THREAD_COUNT, threadArray, TRUE, INFINITE);
        printf("%d\n", g_num);

        CloseHandle(threadArray[0]);
        CloseHandle(threadArray[1]);
        cin.get();
}

編譯會過，但是執行會出現錯誤如下：

First-chance exception at 0x772d5e4f in simpleThreadTest2.exe: 0xC0000008: An
invalid handle was specified.

為什麼呢？

→ rosemary0401:是喔  為什麼呢？
→ stupid0319:你用的WaitForMultipleObjects好像少了點什麼
