Wslay is a WebSocket library written in C. It implements the protocol version 13 described in RFC 6455. This library offers 2 levels of API: event-based API and frame-based low-level API. For event-based API, it is suitable for non-blocking reactor pattern style. You can set callbacks in various events. For frame-based API, you can send WebSocket frame directly. Wslay only supports data transfer part of WebSocket protocol and does not perform opening handshake in HTTP.
Wslay supports:
- Text/Binary messages.
- Automatic ping reply.
- Callback interface.
- External event loop.
Wslay does not perform any I/O operations for its own. Instead, it offers callbacks for them. This makes Wslay independent on any I/O frameworks, SSL, sockets, etc. This makes Wslay portable across various platforms and the application authors can choose freely I/O frameworks.
See Autobahn test reports: server and client.
