libevnet - Evented Networking in C

libevnet is essentially the net module of Node.JS (v0.2.6), implemented in C

Status: Release Candidate. Although there are a few missing features, tigerbot has implemented a simple webserver atop libevn and rumor is that it works well.

Build & Install

make
sudo make install

API

net.Stream

• evn_stream* evn_create_connection(int port, char* address) - create a Unix or TCP stream
  • If port is 0, a Unix Socket is assumed. Otherwise a TCP Socket is assumed.
• struct evn_stream* evn_stream_create(int fd)
• struct evn_stream* evn_create_connection(EV_P_ int port, char* address)
• void evn_stream_priv_on_read(EV_P_ ev_io *w, int revents)
• bool evn_stream_write(EV_P_ struct evn_stream* stream, void* data, int size)
• bool evn_stream_end(EV_P_ struct evn_stream* stream) - closes (and frees) the stream
• void evn_stream_pause(EV_P_ struct evn_stream* stream) // TODO
• void evn_stream_resume(EV_P_ struct evn_stream* stream) // TODO

Event Callbacks

• typedef void (evn_stream_on_connect)(EV_P_ struct evn_stream* stream)
• typedef void (evn_stream_on_secure)(EV_P_ struct evn_stream* stream) // TODO
• typedef void (evn_stream_on_data)(EV_P_ struct evn_stream* stream, void* blob, int size)
• typedef void (evn_stream_on_end)(EV_P_ struct evn_stream* stream)
• typedef void (evn_stream_on_timeout)(EV_P_ struct evn_stream* stream)
• typedef void (evn_stream_on_drain)(EV_P_ struct evn_stream* stream)
• typedef void (evn_stream_on_error)(EV_P_ struct evn_stream* stream, struct evn_exception* error)
• typedef void (evn_stream_on_close)(EV_P_ struct evn_stream* stream, bool had_error)

net.Server

• struct evn_server* evn_server_create(EV_P_ evn_server_on_connection* on_connection)
• int evn_server_listen(struct evn_server* server, int port, char* address) - create a Unix or TCP listener
  • If port is 0, a Unix Socket is assumed. Otherwise a TCP Socket is assumed.
• int evn_server_close(EV_P_ struct evn_server* server) -- closes (and frees) the server

Event Callbacks

• typedef void (evn_server_on_listen)(EV_P_ struct evn_server* server)
• typedef void (evn_server_on_connection)(EV_P_ struct evn_server* server, struct evn_stream* stream)
• typedef void (evn_server_on_close)(EV_P_ struct evn_server* server)
