Substitute for system("cls")`

The question is in the title. Rather then making a call to the OS, is there a more efficient way to do this? Thanks
Edit: Just though of something else to.
Does Sleep(2000); make a call to the OS as well? If so is there another way to do this as well?

Get used to it. Good programmers are in a constant state of confusion.

Both sleep and cls are non-portable.
There is no portable method to clear the screen
Thats because you cant guarauntee the output device is nececerially the screen. e.g on an embedded device it could be a typewriter or something

You mean without moving away from the console for non-sequential output? You could try pdcurses or something similar. At least that way you have more control, but if you're doing any kind of GUI-like interface or advanced drawing, you'd be better off taking the plunge into a modern graphics API.

How exactly are you expecting to talk to the system or any peripherals without making a call to the OS?

On some operating systems and some devices, you can do just that.

Yes, but on the OP's operating system and device? Unlikely.

The last method is probably what you're looking for.

Notes on system() and equivalent functions.
A guy walks up to a rack of fireworks blindfolded. After a short period of time, he mutters something and there's a huge explosion.
First Onlooker: What did he say?
Second Onlooker: I think it was "Is it lit yet?"
