                Notes

                1, Play an audio file.

                #include <nana/audio/player.hpp>

                int main()

                {

    nana::audio::player player(STR("./audio.wav"));

    player.play();  //Play the audio, it waits until the audio is finished.

                }

                2, Play an audio file asynchronously.
                Play the audio when a button is clicked, and it does not block the UI thread.

                #include <nana/gui/wvl.hpp>

                #include <nana/gui/widgets/buttton.hpp>

                #include <nana/audio/player.hpp>

                #include <nana/threads/pool.hpp>

                int main()

                {

    nana::audio::player player(STR("./audio.wav"));

    nana::threads::pool pool(1); //Only 1 thread.

    using namespace nana::gui;

    form fm;

    button btn(fm, nana::rectangle(10, 10, 100, 24));

    btn.caption(STR("Play the audio"));

                    //C++03

    btn.make_event<events::click>(pool_push(pool, nana::make_fun(player, &nana::audio::player::play)));

                    //C++11

    btn.make_event<events::click>(pool_push(pool, [&]()

                           {

                               player.play();

                           }));

    fm.show();

    exec();

                }
