Bill,
I don't know exactly from where I took this info or where it is
documented, but the recv callback is called with a NULL pointer when the
connection has closed.

Hello,
I was wondering why there is no tcp_closed callback function. I
suspect there’s a good reason. I have a PC-based status window using a
socket and I’d like to write to the connection only when the port is
opened. I start logging on the tcp_accept callback and I’d like to
stop on a tcp_closed callback, or some other way to know the
connection has closed. Does anyone have any ideas or thoughts on this?
I probably can watch the pcb state, but I’m trying to have my
application not go further than API calls if I can help it.
Thanks,
Bill
