[lwip-users] Sockets freeing when TCP close abnormally

[Jackie Wang]

Hi all,

I have a question about when the TCP is closed accidentally, e.g. hit 
the max retransmission, so the TCP/IP will close, but the socket seems 
to remain unchanged.

So which layer is responsible of freeing this "dead" socket? Application 
layer? Or LWIP's socket layer can do it somehow?


Best regards,
Jackie
