This function is used to open an UDP/IP socket.
- module

The option makes it possible for the user to provide their own callback module. The functions receive_message/4 or process_received_message/4 of this module is called when a new message is received. Which one depends on the size of the message:
- small
receive_message
- large
process_received_message
Default value is megaco.
Types
Handle = socket_handle()
Msg
This function is used for closing an active UDP socket.
Types
Handle = socket_handle()
Socket = inet_socket()
This function is used to convert a socket_handle() to a inet_socket(). inet_socket() is a plain socket, see the inet module for more info.
Types
Handle = socket_handle()
Host = {A,B,C,D} | string()
Port = integer()
Creates a send handle from a transport handle. The send handle is intended to be used by megaco_udp:send_message/2.
Types
SendHandle = send_handle()
Message = binary() | iolist()
Sends a message on a socket. The send handle is obtained by megaco_udp:create_send_handle/3. Increments the NumOutMessages and NumOutOctets counters if message successfully sent. In case of a failure to send, the NumErrors counter is not incremented. This is done elsewhere in the megaco app.
Types
Handle = socket_handle()
Stop receiving incoming messages on the socket.

Reason = term()
Retreive the UDP related (SNMP) statistics counters.
Types
SendHandle = send_handle()
Reset all TCP related (SNMP) statistics counters.
