使PlaySound畅通无阻 [英] Make PlaySound non-blocking

问题描述

我一直在测试声音，我注意到 PlaySound 正在阻止，即它等待直到声音播放完毕才返回.

I've been testing sounds and I noticed that PlaySound is blocking, i.e. it waits until the sound has finished playing to return.

#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，但是它等待输出此声音很酷"，直到声音播放完毕为止.我该如何做呢?

This code plays the sound, but it waits to output "this sound is cool" until after the sound has finished playing. How can I make it not do that?

推荐答案

异步播放声音:

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

从 MSDN 文档:

声音异步播放，开始发出声音后， PlaySound 立即返回.要终止异步播放的波形声音，请在 pszSound 设置为 NULL 的情况下调用 PlaySound .

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.
