[lwip-devel] [task #10088] Correctly implement close() vs. shutdown()

[Simon Goldschmidt]

Follow-up Comment #14, task #10088 (project lwip):

> or shutdown(RD) discard any data the process has not yet read

So I guess discard only means "don't pass to application", but no "abort the
connection".

Both shutdowns are already implemented that way. Thanks for the link.

Still, I don't know whether to send RST if data is coming in after calling
tcp_close(). I'll see if I can find anything about that in the book...
