Follow-up Comment #3, bug #28853 (project lwip):
> actually my patch is wrong because it returns -1 on close.
I just noticed that, too when writing a test for it. Seems I have been too
fast checking in the fix ;-)
> on receive time-out, netconn_recv() returns ERR_TIMEOUT (which is a fatal
error !)
It's not (any more? I think I changed that some time ago...). I've fixed
err_to_errno_table to convert ERR_TIMEOUT to EWOULDBLOCK. Thanks for finding
that, too!
