Detailed Description

Callbacks for reading a file from the outstation asynchronously.

Field Documentation

void(* dnp3_file_reader_t::aborted) (dnp3_file_error_t, void *)

Called when the transfer is aborted before completion due to an error or user request.

Parameters

error	Error describing why the transfer aborted
ctx	Context data

bool(* dnp3_file_reader_t::block_received) (uint32_t, dnp3_byte_iterator_t *, void *)

Called when the next block is received.

May optionally abort the transfer. This allows the application abort on internal errors like being or by user request.

Parameters

block_num	The block number which increments as the transfer proceeds
data	iterator of bytes in the block
ctx	Context data

void(* dnp3_file_reader_t::completed) (void *)

Called when the transfer completes successfully.

Parameters

ctx	Context data

void* dnp3_file_reader_t::ctx

Context data.

void(* dnp3_file_reader_t::on_destroy) (void *arg)

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

Parameters

arg	Context data

bool(* dnp3_file_reader_t::opened) (uint32_t, void *)

Called when the file is successfully opened.

May optionally abort the operation by returning false

Parameters

size	Size of the file returned by the outstation
ctx	Context data
