## What it is
CppNet is a cross-platform, multithreaded C++11 network library implementing the proactor pattern for asynchronous TCP I/O. It uses epoll, wepoll (IOCP), and kqueue under the hood and exposes a small socket-like callback API supporting IPv4 and IPv6.

## Use cases
- build a high-performance TCP server in C++
- write asynchronous network clients and servers with callbacks
- implement a simple HTTP server on Linux, Windows, and macOS
- handle thousands of concurrent socket connections efficiently
- build an RPC or file-transfer service over TCP
- replace raw epoll/kqueue/IOCP code with a portable abstraction

## When to choose
- you need a lightweight, portable async TCP library in modern C++ with minimal dependencies
- you want proactor-style asynchronous callbacks similar to system socket APIs
- you need cross-platform support for epoll, kqueue, and IOCP/wepoll from one codebase
- you want per-socket memory pooling and time-wheel timers built in

## When to avoid
- you need full-featured application protocols like HTTP/2, TLS, or WebSockets out of the box
- you prefer a large, widely-adopted ecosystem like Boost.Asio with extensive documentation
- your project requires UDP, QUIC, or other non-TCP transports
- you need commercial-grade support or a very large contributor community
