Epoll FR: notify on socket state updates #946
Description
As an application I want to send some message over SRT. This message might take several SRT data packets.
I a non-blocking mode I can receive a notification that I can write to a socket, but I might not have enough space in the sender buffer to store the whole message. I would like to subscribe to the next event when the size of the sender buffer is increased, so that I can check again if I can write my message.
Something like "state update event".
For network bonding the same might be useful to get a notification about new connections to accept.
Low priority for notifications on the sender buffer space changes.
Medium priority for notifications on new connections in a socket group to accept.
