[lwip-users] netconn_recv and client disconnect

[markus . forrer]

I'm using lwip 1.4.1 in a RTOS environment (uc/OS-II) as the follow:

 

while ((error = netconn_recv(connection, &receiveBuffer)) == ERR_OK)

{

    // receiving data

}

// client has disconnected

 

Receiving data works fine. But if the connection will be closed by the remote client, netconn_recv returns ERR_OK anyway. I can't differ from 'receiving data' and 'client disconnect'.

 

Any hints?

 

Thanks a lot!
