Did you test the return value of getsockopt() to make sure it even succeeded
to begin with?  You should also initialize your int variable, otherwise it
will get a random value, which if getsockopt() fails, your code will
interpret incorrectly:

    int sockType = 0,
    if( getsockopt(s , SOL_SOCKET , SO_TYPE,  (char FAR *)&sockType,
sizeof(sockType) == 0 )
        // use sockType as needed
    else
        // error

Also, how are you creating/retreiving the socket descriptor to begin with?
