This module contains functions for working with sequencer queue. Reference: http://www.alsa-project.org/alsa-doc/alsa-lib/group___seq_queue.html
General Queue Functions
|:: T mode|
|-> Maybe T|
prototype event that may provide timestamp, source queue
|-> IO ()|
startstopcontinue a queue
In the prototype event you can provide additional information. The prototype event does not need to be a queue control event, this part is ignored anyway. In the prototype event you may also specify a queue. This is the queue that the timestamp of the prototype event refers to. This way you can control the target queue using timing from another queue.
