Good article. I’d like to add that similar queues are widely used in all multimedia, not just games. This library https://github.com/Const-me/Vrmac/tree/maste

Good article. I’d like to add that similar queues are widely used in all multimedia, not just games. This library https://github.com/Const-me/Vrmac/tree/master/VrmacVideo https://github.com/Const-me/Vrmac/tree/master/VrmacVideo uses queues to coordinate 3 threads, one decoding video by pumping V4L2 kernel queues, another one decoding audio and playing it with ALSA, and the main thread rendering frames with GLES. Two of my queues are thin wrappers around mq_send / mq_receive Linux APIs.
