Detailed Description

Callbacks to user code that determine how the server processes connections.

Field Documentation

accept

void(* dnp3_connection_handler_t::accept) (const char *, dnp3_accept_handler_t *, void *)

Filter the connection solely based on the remote address.

Parameters

remote_addr	Socket address of the remote outstation, e.g. 192.168.0.22:51532
acceptor	Class used to handle the accept
ctx	Context data

accept_with_link_id

void(* dnp3_connection_handler_t::accept_with_link_id) (const char *, uint16_t, uint16_t, dnp3_identified_link_handler_t *, void *)

Filter the connection based on the source and destination of the first link-layer frame.

Parameters

remote_addr	Socket address of the remote outstation, e.g. 192.168.0.22:51532
source	Source address from the frame
destination	Destination address from the frame
acceptor	Class used to handle the accept
ctx	Context data

ctx

void* dnp3_connection_handler_t::ctx

Context data.

on_destroy

void(* dnp3_connection_handler_t::on_destroy) (void *arg)

Callback when the underlying owner doesn't need the interface anymore.

Parameters

arg	Context data

start

void(* dnp3_connection_handler_t::start) (const char *, dnp3_master_channel_t *, void *)

Start a communication session that was previously accepted using only the socket address.

Warning

You must add associations and/or enable the channel from a different thread than this callback as those methods cannot be called on the Tokio runtime

Parameters

remote_addr	Socket address of the remote outstation, e.g. 192.168.0.22:51532
channel	Class used to control the channel
ctx	Context data

start_with_link_id

void(* dnp3_connection_handler_t::start_with_link_id) (const char *, uint16_t, uint16_t, dnp3_master_channel_t *, void *)

Start a communication session that was previously accepted using link identity information.

Warning

You must add associations and/or enable the channel from a different thread than this callback as those methods cannot be called on the Tokio runtime

Parameters

remote_addr	Socket address of the remote outstation, e.g. 192.168.0.22:51532
source	Source address from the frame
destination	Destination address from the frame
channel	Class used to control the channel
ctx	Context data
