[lwip-devel] [patch #5780] Implement SO_RCVTIMEO on UDP sockets/netconn

[Simon Goldschmidt]

Follow-up Comment #1, patch #5780 (project lwip):

Implementing such general socket options (derived from linux etc.) is fine
for me, as long as you can turn it off to save code space if you don't need
it.
But rather than changing the mbox api for this purpose, I would like to
introduce a new function for this (sys_mbox_fetch_timeout or something) which
returns int instead of void to let the caller know if it worked. You have it
this way with most embedded operating systems, anyway.
In sys.c, sys_mbox_fetch can simply call the new function with timeout=0.

I can't read the source code in this post though, since it is not formatted.
