Mongoose is a multi-protocol networking library that implements non-blocking, asyncronous IO and provides event-based API. It has three basic data structures:
struct mg_mgris an event manager that holds all active connectionsstruct mg_connectiondescribes a connectionstruct mbufdescribes data buffer (received or sent data)
Connections could be either listening, outbound or inbound. Outbound
connections are created by mg_connect() call. Listening connections are
created by mg_bind() call. Inbound connections are those accepted by a
listening connection. Each connection is described by struct mg_connection
structure, which has a number of fields like socket, event handler function,
send/receive buffer, flags, et cetera.
Mongoose usage pattern is to declare and initialize event manager, create
connections and create an event loop by calling mg_mgr_poll() in a loop.
mg_mgr_poll() iterates over all sockets, accepts new connections, sends and
receives data, closes connections, and calls event handler functions for the
respective events.
