Shouldn't this pthread_mutex_unlock(&queue_mutex); be moved after the uv_async_send(async); condition? 👍 1 Author josephg commented Mar 25, 2019 • edited I don't think so. I mean, this is the heart of this problem - as far as I can tell from the documentation, uv_async...
(I see but if I never close the async, and of course I can't use data for anything useful and it might as well be null and just reference a static container that contains a queue with the object who's callback is to be called for the message received?
