c++ - 使 PlaySound 成为非阻塞的

Question

我一直在测试声音，我注意到 PlaySound 是阻塞的，即它会等到声音播放完毕才返回。

#include <iostream>
#include <Windows.h>
#include <mmsystem.h>

int main()
{
    PlaySound("E:/Downloads/eb_sfx_archive/brainshock.wav", 0, SND_FILENAME);
    std::cout << "this sound is cool";
    Sleep (500);
    std::cout << "\nmeh... not really";
    return 0;
}

此代码播放声音，但它会等待输出“这个声音很酷”，直到声音播放完毕。我怎样才能让它不那样做？

异步播放声音:

PlaySound(L"E:\\Downloads\\eb_sfx_archive\\brainshock.wav", NULL, SND_ASYNC);

来自MSDN文档:

The sound is played asynchronously and PlaySound returns immediately after beginning the sound. To terminate an asynchronously played waveform sound, call PlaySound with pszSound set to NULL.
