MODBUS_RECEIVE_CONFI(3) Libmodbus Manual MODBUS_RECEIVE_CONFI(3)
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.
