About:
epoll-shim is a userspace compatibility layer that implements the Linux epoll API using BSD kqueue. It allows software designed for Linux to run on macOS and other BSD-derived systems without modification. This library provides a bridge for cross-platform applications that rely on epoll for efficient event notification.

Key Features:

Implements Linux epoll API on top of kqueue
Designed for high performance and low overhead
Enables seamless porting of Linux software to macOS/BSD
Small, focused library with a simple API

Use Cases:

Porting Linux network services to macOS
Running Linux-native server applications on BSD systems
Developing cross-platform event-driven software

Alternatives:

libev – A full-featured cross-platform event loop library, whereas epoll-shim specifically targets API compatibility for epoll.
porting code to use kqueue directly – More work but offers native performance and full access to kqueue features.
