This is required to distinguish input interface for multicast traffic and select correct output interface for outgoing traffic (advertisements). http://savannah.nongnu.org/bugs/?49662 removed ability to receive multicast traffic on on interface-bound sockets (making the previous change useless, hence the revert), so for LWIP 2.0.1 and newer multicast packets can only be received on INADDR_ANY listeners. User is then required to distinguish input interface in the receive path. This information is only available in the udp_recv callback, so we must pass this down to dns-sd library somehow, and priv_2 is the how. It is normally used for DNS resolver state, and is never used on listening sockets. We thus avoid growing the mg_connection structure.
Mongoose - Embedded Web Server / Embedded Networking Library
Mongoose is ideal for embedded environments. It has been designed for connecting devices and bringing them online. On the market since 2004, used by vast number of open source and commercial products - it even runs on the International Space station! Mongoose makes embedded network programming fast, robust, and easy.
Connectivity is vital for software and embedded devices, but there are many pitfalls to consider when embedding a web server. This white paper breaks down on the top 9 things to avoid when embedding a web server.
