Maybe, but there is the internal buffer. Also, most I/O happens in files not consoles

std::endl is used in output streams in C++ to end the line, using the os specific line termination sequence, and flush the buffer.

The later one is a performance issue in many cases, why the use of "\n" is considered preferred

We are using relativ old Hardware, old thinkpads. They would not be able to run Windows 10 or 11 bare metal ;)

This does not help with Ruida Controllers and fiber Lasers. Both things I have at my company and we don’t have any Windows System.

That is such a shame. And since we need to talk over usb, wine will not work either 😞
