MODBUS_SET_RESPONSE_(3)        Libmodbus Manual        MODBUS_SET_RESPONSE_(3)


NAME

       modbus_set_response_timeout - set timeout for response


SYNOPSIS

       int modbus_set_response_timeout(modbus_t *ctx, struct timeval
       *timeout);


DESCRIPTION

       The modbus_set_response_timeout() function shall set the timeout
       interval used to wait for a response. If the waiting before receiving
       the response is longer than the given timeout, an error will be raised.


RETURN VALUE

       The function shall return 0 if successful. Otherwise it shall return -1
       and set errno.


EXAMPLE

           struct timeval old_response_timeout;
           struct timeval response_timeout;

           /* Save original timeout */
           modbus_get_response_timeout(ctx, &old_response_timeout);

           /* Define a new and too short timeout! */
           response_timeout.tv_sec = 0;
           response_timeout.tv_usec = 0;
           modbus_set_response_timeout(ctx, &response_timeout);
