The socket will report an error whenever you tr to read/write on the invalid 
connection.

There is.  However, abnormal disconnects are very difficult to detect in a 
timely manner.  It may take several hours for the OS to detect that a socket 
connection has been lost.  In the meantime, the socket happily continues 
accepting read/write requests.  The reads will return no data, and the 
writes will be buffered and never sent.  As such, you should be implementing 
your own timeouts in your code, and also implemennting keepalives into your 
data protocol if possible.  Have the client send a keepalive packet 
periodically, and have the server reply to it.  If the client does not 
receive a reply, then close the connection and reconnect.  If the server 
does not receive any data from a client for a period of time, then close the 
connection and wait for a new connection.
