mg_bind_opt() mg_bind_opt func struct mg_connection *mg_bind_opt(struct mg_mgr *mgr, const char *address, mg_event_handler_t handler, struct mg_bind_opts opts);

Create listening connection.

address parameter tells which address to bind to. It's format is the same as for the mg_connect() call, where HOST part is optional. address can be just a port number, e.g. :8000. To bind to a specific interface, an IP address can be specified, e.g. 1.2.3.4:8000. By default, a TCP connection is created. To create UDP connection, prepend udp:// prefix, e.g. udp://:8000. To summarize, address paramer has following format: [PROTO://][IP_ADDRESS]:PORT, where PROTO could be tcp or udp.

See the mg_bind_opts structure for a description of the optional parameters.

Return a new listening connection, or NULL on error. NOTE: Connection remains owned by the manager, do not free().
