superpowered - 超级强大的高级音频播放器。如何等待缓存？

Question

我正在使用超级强大的 sdk 来播放音频文件。我需要等待 SuperpoweredAdvancedAudioPlayer 缓存文件。这是我尝试过的伪代码：

void loading (shared_ptr<SuperpoweredAdvancedAudioPlayer> player, string path)
{
    player->open(path.c_str());
    player->cachePosition(0, 0);
}

int main ()
{
    string filePath = "/path/file.wav";

    shared_ptr<SuperpoweredAdvancedAudioPlayer> player;
    player = make_shared<SuperpoweredAdvancedAudioPlayer>(nullptr, nullptr, 44100, 10, 2, 0);
    thread Loading(loading, player, filePath);
    char *tmp = (char*)&player->waitingForBuffering;
    Loading.join();
    while (*tmp) {usleep(10000);}

    return 0;
}

它对我不起作用。waitingForBuffering 始终为真。什么是有效的等待方式？
