==============================


NAME
----
modbus_receive_confirmation - receive a confirmation request


SYNOPSIS
--------
*int modbus_receive_confirmation(modbus_t *'ctx', uint8_t *'rsp');*


DESCRIPTION
-----------
The _modbus_receive_confirmation()_ function shall receive a request via the
socket of the context 'ctx'. This function must be used for debugging purposes
because the received response isn't checked against the initial request. This
function can be used to receive request not handled by the library.


RETURN VALUE
------------
The _modbus_receive_confirmation()_ function shall store the confirmation
request in 'rsp' and return the response length if sucessful. The returned
request length can be zero if the indication request is ignored (eg. a query for
another slave in RTU mode). Otherwise it shall return -1 and set errno.
