[lwip-devel] [bug #20021] conn->sem is only signaled one-way

[Frédéric Bernon]

Follow-up Comment #3, bug #20021 (project lwip):

Note that netconn_close is not used at socket layer. But if you use it, you
have to be sure that the tcp_close have success.

If during the close, there is a ERR_MEM, to avoid to consumne cycles to
retry, you wait the next "poll_tcp"...
