ALLEGRO_SAMPLE_INSTANCE - Allegro 5 API
typedef struct ALLEGRO_SAMPLE_INSTANCE ALLEGRO_SAMPLE_INSTANCE;
An ALLEGRO_SAMPLE_INSTANCE object represents a playable instance of a predefined
sound effect. It holds information about how the effect should be played:
These playback parameters consist of the looping mode, loop start/end points,
playing position, speed, gain, pan and the playmode. Whether a sample instance
is currently playing or paused is also one of its properties.
An instance uses the data from an ALLEGRO_SAMPLE(3alleg5) object. Multiple
instances may be created from the same ALLEGRO_SAMPLE. An ALLEGRO_SAMPLE must
not be destroyed while there are instances which reference it.
To actually produce audio output, an ALLEGRO_SAMPLE_INSTANCE must be attached to
an ALLEGRO_MIXER(3alleg5) which eventually reaches an ALLEGRO_VOICE(3alleg5)
