Peter,

This works for me:

    /* Detect dead connections */
    int   keepalive = 1 ;
    r = setsockopt(sock, SOL_SOCKET, SO_KEEPALIVE,
                   (char *)&keepalive,
                   sizeof(keepalive)) ;

recv() will now return ECONNABORTED when the host 
disconnects.

Best regards,
Joris
