SYNOPSIS

       int modbus_get_response_timeout(modbus_t *ctx, uint32_t *to_sec, uint32_t *to_usec);

DESCRIPTION

       The modbus_get_response_timeout() function shall return the timeout interval used to wait

RETURN VALUE

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

EXAMPLE

           uint32_t old_response_to_sec;
           uint32_t old_response_to_usec;

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

           /* Define a new and too short timeout! */
           modbus_set_response_timeout(ctx, 0, 0);
