https://libwebsockets.org/pipermail/libwebsockets/2019-April/007937.html thanks to Bruce Perens for noting it. This doesn't change the intention or status of the CC0 files, they were pure CC0 before (ie, public domain) and they are pure CC0 now. It just gets rid of the (C) part at the top of the dedication which may be read to be a bit contradictory since the purpose is to make it public domain. |

lws minimal ws server raw vhost
This demonstrates setting up a vhost to listen and accept raw sockets. Raw sockets are just sockets... lws does not send anything on them or interpret by itself what it receives on them. So you can implement arbitrary tcp protocols using them.
This isn't very useful standalone as shown here for clarity, but you can freely combine a raw socket vhost with other lws server and client features and other vhosts handling http or ws.
Becuase raw socket events have their own callback reasons, the handlers can be integrated in a single protocol that also handles http and ws server and client callbacks without conflict.
