Hi again,
I'm still unable to reproduce the proper behavior or the behavior as
Frédéric described below. The point is still that netconn_connect()
returns ERR_OK even if there is nobody listening on the other side.
What happens behind the scenes is that a message will get posted to the
tcpip thread's mailbox, and the calling thread should wait on a
per-connection semaphore (called op_completed) for the tcpip thread to
indicate that the operation has completed.
Perhaps somehow that semaphore did not have the correct state before the
call - perhaps it had already been signaled? Or had not been created in
the port with a value of 0 - in netconn_alloc() in api_msg.c, lwIP
requests it to be created with a value of 0, but perhaps something doesn't
do it right in the port?
