Asynchronous TCP server using C++ and Linux kernel IO interface io_uring via liburing

• build - mkdir build && cd build && cmake .. && make

• run - ./tcp-server 8080 or your port of choice.

• connect - telnet 0.0.0.0 8080 or telnet localhost 8080

Specification

• Supports numerous connections asynchronously without any threading, only through io_uring requests.

• Received messages are written into build/<port_num>.txt.

• For each message the server replies with ACCEPTED delayed by 3 seconds.

• Each message is delayed asynchronously using liburing, regardless of any other messages or connections.

• Server shuts down when the last connection is closed.
