[lwip-devel] tcp_close() in callback API

When using the callback API of lwIP, using the stack against itself and one of 
the sides does a tcp_close(), how is the other side supposed to get informed 
that it too should tcp_close()? Under normal circumstances, in a non callback 
API, the non closing side would get an EOF when reading from the connection but 
in a callback case no such reads are done. Shouldn't there be some callback 
notification in the ESTABLISHED case in tcp_process before going to the 

As it is today, using the callback API, a connection has no way of telling if 
the connection was closed.
