[lwip-users] query netconn connection ...

[Teratux]

Hi .. I have an multithreaded application that I managed to create to use an existing connection resource using the timeout option on the listener thread.  When the timeout expires the connection wait I want to query in the code below if that really ocurred or some error of another sort ( a network failure of some sort or a disconnection from the other party ).  I'm using lwIP on FreeRTOS ...

in = netconn_recv(pNewConnection);

                if ( in != NULL )
                {
                    netbuf_data(in, (void*)&pBuff, &len);

                    i = 0;
                    while( i < len )
                    {
                        if( xQueueSend( handleUpr, &pBuff[i++], 200 ) == pdPASS )
                        {
                            vParTestToggleLED(1);
                        }
                    }
                    netbuf_delete(in);
                }

                // HERE

In the "// HERE" comment I want to verify if the netconn_recv command really timed out or if an error ocurred.  How can I accomplish this ... ?

Thanks ...
