Re: [libmicrohttpd] tiny websocket above LMHD

[silvioprog]

Hello again José,

just to share two WS libraries I found:

1. https://github.com/tatsuhiro-t/wslay

2. https://libwebsockets.org

I have never tried these libraries before... maybe they could help to create a cross-platform WS layer to use with MHD.

best,

Hello José, thanks for answering.

Sorry for resend, I don't know why the Gmail client sent it to your particular e-mail. 🤔

So, I have a question. Could I send a feature-request at lmhd-ws/issues?  If so, I'll open a new issue as feature-request to build the library on Windows using the MSYS2 tools http://www.msys2.org .

Thank you! (y)

Perhaps some "signal(SIGPIPE, SIG_IGN);" is missing

Yep, iov feature could be removed probably. It doesn't brings much at
the end.

I would be happy if it could be done in the context of
https://gitlab.com/jobol/lmhd-ws

But it is a matter of choice I know. If you want please open issues to
track your features: https://gitlab.com/jobol/lmhd-ws/issues

Best regards
José
