Detailed Description

Callbacks received when reading coils or discrete inputs.

On success, the iterator yields exactly the requested number of values in ascending, contiguous address order, beginning at the start of the requested rodbus_address_range_t. A response containing too few or too many values fails the request.

Field Documentation

ctx

void* rodbus_bit_read_callback_t::ctx

Context data.

on_complete

void(* rodbus_bit_read_callback_t::on_complete) (rodbus_bit_value_iterator_t *, void *)

Invoked when the asynchronous operation completes successfully.

Parameters

result	Iterator over the values read from the server, in ascending address order
ctx	Context data

on_destroy

void(* rodbus_bit_read_callback_t::on_destroy) (void *arg)

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

Parameters

arg	Context data

on_failure

void(* rodbus_bit_read_callback_t::on_failure) (rodbus_request_error_t, void *)

Invoked when the asynchronous operation fails.

Parameters

error	Enumeration indicating which error occurred
ctx	Context data
