【问题描述】：

我正在使用 SDL_mixer 处理 this tutorial 的音频，一切顺利。

后来我决定在探索中尝试、玩、学习，所以我做了一个非常相似的程序，有两个声道，让我播放一些视频游戏音乐，并按下按钮播放游戏音效。

然后我开始享受乐趣和按钮捣碎只是为了愚蠢并测试程序。我开始按钮混搭多个按钮非常快，然后在这样做大约 5 秒后，程序意外关闭。

从大约 2 个月前的那个日期开始，我一直无法在使用 SDL_mixer 的计算机上运行 -anything-。我试过用 SDL_mixer 创建新项目，我重新下载了所有的 SDL 和 SDL_mixer，甚至问过this question on the sdl forums。

我正要重新格式化我的整个计算机以使其再次工作，这是 - 不 - 好的。扩展库不应该强迫某人重新格式化，尤其是当这个问题可能会传递给最终用户下载和使用该程序时。

我使用的是 Windows 7 64 位；微软 Visual Studio 2012 专业版； C++；和 SDL 1.x

另外，如果有人知道出了什么问题，我该如何解决这个问题，防止它再次发生，并安全地使用声音，这样我就不会在用户的计算机上造成问题？

我用来初始化混音器的行如下：

//Initialize SDL_mixer 
if( Mix_OpenAudio( 22050, MIX_DEFAULT_FORMAT, 2, 4096 ) == -1 ) 
 
    return false; 

启动程序后调试器吐出的行并立即关闭：

附：有没有一种更简单的方法来表示大段代码，而不必在每行前面手动复制过去 4 个空格？这花了一段时间._.;

【问题讨论】：

关于缩进代码sn-ps，在编辑框的工具栏中有一个看起来像两个大括号的按钮，选择要缩进的文本并按下该按钮。

非常感谢！~我相信这将是一个完整的生命拯救者！~

如果在第 195 行（bool quit = false;，main() 的第一个非注释行）放置断点，它会被命中吗？

是的！~确实如此。哦，我的天哪 -THANKYOU- 太多了！！！！~ 因为我能够在那里放置一个断点，所以我能够成功调试我的程序并且它工作了！！！~ 非常感谢！！！~ 直到现在我无法让任何断点工作，程序会在它中断调试之前退出，但是那个 ONE 点工作，让我调试和修复问题。然而，我 - 不明白的是，其他使用 SDL_mixer 且一直在工作的程序也崩溃并遇到了同样的问题。

问题出在哪里？

【参考方案1】：

感谢 genpfault 的建议，我能够找到解决此问题的方法。

事实证明，解决方案是当程序从过载的声道崩溃时，因为声音必须通过按键激活，排队的按键被附加到程序的 源代码，因为 Visual Studio 会在崩溃后自动抓取“窗口焦点”并“捕获”多余的字符。

这些字符恰好被附加到程序一开始的 SDL_mixer 函数的第一个错误检查行之一的字符串文字中，因此它不会为编译器引发语法错误；错误检查行只是说“不，加载的文件与该字符串不完全匹配，因此关闭程序”，这导致程序在我的断点注册并允许我调试之前退出。

终于解决了这个问题，这绝对是一种解脱。

谢谢 genpffault 和 stack-overflow！~

【讨论】：

啊哈哈！~不过，我只是因为你的建议才抓住它。我在那个点之前和之后都设置了断点，但之前从来没有 - 在 - 那个点，并且那个点确实有效。由于我还是新手，我还没有意识到这一点的知识或专业知识，但是感谢您的建议，我学到了宝贵的一课。所以谢谢：D
