In this lesson we will cover a single function, PeekMessage(), and how this function differs from its evil twin, GetMessage().
主要讲的就是PeekMessage()和GetMessage()两个获取消息函数的不同，而对于游戏编程，我们更需要的是前者。这一点已经在Lesson3中说了，不再做赘述。

简单上两个图片再次说明两个函数获取消息的差别吧：
GetMessage():
这里写图片描述

PeekMessage():
这里写图片描述

如何将PeekMessage()函数补充到我们之前的消息循环中呢？

// enter the main loop:

// this struct holds Windows event messages
MSG msg = {0};

// Enter the infinite message loop
while(TRUE)
{
    // Check to see if any messages are waiting in the queue
    if(PeekMessage(&msg, NULL, 0, 0, PM_REMOVE))
    {
        // translate keystroke messages into the right format
        TranslateMessage(&msg);

        // send the message to the WindowProc function
        DispatchMessage(&msg);

        // check to see if it's time to quit
        if(msg.message == WM_QUIT)
            break;
    }
    else
    {
        // Run game code here
        // ...
        // ...
    }
}
