当多个句柄同时发出信号时,WaitForMultipleObjects的行为

#include<windows.h>
#include<stdio.h>

int main()
{
    HANDLE hMutex1 = CreateMutex(NULL, FALSE, TEXT("Mutex1"));
    HANDLE hMutex2 = CreateMutex(NULL, FALSE, TEXT("Mutex2"));
    HANDLE hMutex3 = CreateMutex(NULL, FALSE, TEXT("Mutex3"));

    // 等待多个对象，直到其中一个变为已终止状态
    DWORD dwWaitResult = WaitForMultipleObjects(3, 
        hMutexArray, FALSE, INFINITE);

    switch (dwWaitResult)
    {
        case WAIT_OBJECT_0:
            // hMutex1已终止
            break;
        case WAIT_OBJECT_0 + 1:
            // hMutex2已终止
            break;
        case WAIT_OBJECT_0 + 2:
            // hMutex3已终止
            break;
        default:
            printf("WaitForMultipleObjects 失败。\n");
            break;
    }

    // 关闭句柄
    CloseHandle(hMutex1);
    CloseHandle(hMutex2);
    CloseHandle(hMutex3);

    return 0;
}
