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

[Simon Goldschmidt]

Follow-up Comment #9, task #10088 (project lwip):

OK but when using tcp_recved(), we couldn't differ between raw API- and
netconn/socket-applications. Therefore, I think it would be OK to require raw
API apps to call tcp_recved before calling tcp_close - unless they don't care
for the RST.

> There is no buffering in the raw API.

There is struct tcp_pcb.refused_data...
