Method sendLine

FluidNC/src/Channel.cpp:295–302

This overload is used primarily with fixed string values. It sends a pointer to the string whose memory does not need to be reclaimed later. This is the most efficient form, but it only works with fixed messages.

// This is the most efficient form, but it only works
// with fixed messages.
void Channel::sendLine(MsgLevel level, const char* line) {
    if (outputTask) {
        LogMessage msg { this, (void*)line, level, false };
        while (!xQueueSend(message_queue, &msg, 10)) {}
    } else {
        print_msg(level, line);
    }
}

// This overload is used primarily with log_*() where
// a std::string is dynamically allocated with "new",
