Sock.Rxlen R/O Property
|Top Previous Next|
The on_sock_data_arrival event is generated once the RX buffer is not empty, i.e. there is data to process. There may be only one on_ser_data_arrival event for each socket waiting to be processed in the event queue. Another on_sock_data_arrival event for the same socket may be generated only after the previous one is handled.
If, during the on_sock_data_arrival event handler execution, not all data is extracted from the RX buffer, another on_sock_data_arrival event is generated immediately after the on_sock_data_arrival event handler is exited.
