## What it is
wepoll is a small C library that implements the Linux epoll API on Windows, enabling scalable socket event notification. It is distributed as a single source file and header for easy embedding in cross-platform applications.

## Use cases
- port Linux epoll-based code to Windows
- poll tens of thousands of sockets efficiently on Windows
- build cross-platform event loops without IOCP
- replace select/WSAPoll in Windows networking code
- embed a scalable socket readiness API in a C/C++ project

## When to choose
- you need epoll-compatible socket polling on Windows
- your cross-platform code relies on epoll semantics
- you want a trivially embeddable two-file library

## When to avoid
- you need edge-triggered (EPOLLET) mode, which is unsupported
- you need to poll file descriptors or non-socket handles
- you target Windows versions older than Vista
- you prefer native IOCP-based async I/O designs

## Facets
- artifact type: library
- maturity: maintenance
- function: networking, concurrency, developer-tools
- domain: networking, developer-tools, cross-platform
- platform: windows, cpp, c
- tags: epoll, sockets, event-loop, io-completion-ports, single-file-library
