[lwip-users] Problem with netconn_write

[Uwe Solter]

I already applied patch 4302 but still encounter problems with netconn_write.

The semaphore which is waited on when tcp_sndbuf( conn->pcb.tcp ) returns 0

does not become signalled untill the connection is closed from the peer.

Could somebody explain where in the code under what conditions it is signalled

(Not an essay, just to give me a chance to investigate this further)?
