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
Automatic ping reply.
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.
