Some questions about the raw api:
- When doing a tcp close, when is it safe to destroy my state on
the pcb? It seems like some callbacks can get called after
a tcp_close is done (ie. the tcp_sent callback seems to be
called at times, to acknowledge the FIN?). I need to know
under what conditions I can destroy my state immediately
after a tcp_close and under what conditions the state must
be maintained until after callbacks occur, and what callbacks
can occur.
- if a tcp_close returns an out of memory error (the only
error that can occur, according to the documentation),
what conditions can I rely on to trigger a retry?
Will there be a callback that will indicate that I
should try again, and if so, which?
- Are there any callbacks that can occur after a udp close?
