Struct EventDataQueue

pub struct EventDataQueue { /* private fields */ }

A boxed object to express data of queue event.

A EventDataQueue is a boxed object to express data of queue event. The instance of object is one of data properties in event.

The object wraps struct snd_seq_ev_queue_control in UAPI of Linux sound subsystem.

GLib type: Boxed type with copy-on-clone semantics.
