On_sock_overrun Event

Top  Previous  Next



Data overrun has occurred in the RX buffer of the socket.

Normally, overruns can only happen for UDP communications as UDP has no "data flow control" and, hence, data overruns are normal. Another on_sock_overrun event on a particular socket is never generated until the previous one is processed. When the event handler for this event is entered the sock.num is automatically switched to the socket on which this event was generated.
