+Loads dynamic libraries and prepares them for use. Flags should be one or more flags from init flags OR'd together. +It returns the flags successfully initialized, or 0 on failure.

const SDL_version * SDL::Mixer::linked_version () +$version = SDL::Mixer::linked_version(); + +++
linked_versiongives you the major-, minor-, and patchlevel for SDL_mixer. This way you can check if e.g. init() and quit() +are available.Example:
+use SDL::Mixer; + use SDL::Version; + + my $version = SDL::Mixer::linked_version(); + + printf("%d.%d.%d\n", $version->major, $version->minor, $version->patch); # prints "1.2.8" for me
int SDL::Mixer::open_audio ( frequency, format, channels, chunksize ) +my $audio_opened = SDL::Mixer::open_audio( $frequency, $format, $channels, $chunksize ); + +++
open_audiowill initialize SDL_mixer if it is not yet initialized, see note. SDL_mixer may not be able to provide the exact specifications +your provided, however it will automatically translate between the expected format and the real one. You can retrieve the real format using +query_spec.Returns 0 on success, -1 on error.
+Note: You must not use
+AUDIO_S16,AUDIO_U16,AUDIO_S16LSB, orAUDIO_U16LSB.They are not portable, and SDL will not return an +error code when they fail. The result will be a horrible staticy noise. You can usually useAUDIO_S16SYS, though not always. Future versions +of SDL should take this parameter only as a hint, then read back the value that the OS (for example, OSS or ALSA) has chosen to use in case the +desired audio type is not supported.Note: When already initialized, this function will not re-initialize SDL_mixer, nor fail. It will merely increment the number of times +SDL::Mixer::close_audio must be called to actually get it to uninitialize. This serves as a very simplistic method for multiple application +components to use SDL_mixer without necessitating a great deal of inter-component awareness. Be warned however that in such a situation, the +latest components to initialize SDL_mixer will probably not get the SDL_mixer settings they're expecting.
+Example:
+use SDL; + use SDL::Mixer; + + printf("Error initializing SDL_mixer: %s\n", SDL::get_error()) unless SDL::Mixer::open_audio(44100, AUDIO_S16, 2, 1024) == 0;
void SDL::Mixer::close_audio () +SDL::Mixer::close_audio();+Close the mixer and halting all playing audio. This function does not return anything.
