Detection and handling of tcpip related problems

Gaby Levy
Intellectual 410 points

Hi, 

I made a simple application that opens a socket, connects to a tcpip server, then answers to messages from the server - it works fine.

Now I want to cover problems that may happen - I would like to know how to detect them (I guess hooks) and what is the handling.

I can think now on two possible problems , please let me know if there are more:

1) disconnection from server

2) socket closed (can this happen?)

Thanks in advance!

Board: EVMC6748 (I am using the TMS320C6748 DSP).

I am connected using the ethernet port to my router.

    Gaby Levy,

    When you disconnect the TCP socket, should be close the socket handle using fdClose.
    SOCKET slistenData = INVALID_SOCKET; //declaration

    If the connection got an error or disconnect, close the socket.
    fdClose( slistenCmd );
    slistenCmd = INVALID_SOCKET;
