42_irc

Internet Relay Chat server

RFC compliant IRC protocol server written in C++ using BSD libc

Features

• Kernel event notification mechanism provided by kevent & kqueue

• Efficient single-threaded synchronous operations

• Flood-safe execution

• Empathetic buffer management for clients struggling with data transmission

POSIX?

No, unfortunately

We wanted to take advantage of a modern and smart kernel notification system that could handle UNIX-signals as well

This led us to GNU epoll and BSD kevent. Both of these notification systems use non-POSIX compliant syscalls and therefore are not portable-friendly

Interesting discussions on the topic:

• Choosing between portability and innovation
• kqueue vs epoll
