Could C++ develop rtos?

[stereoMatching]

Are there any rtos developed by C++?
Not sure if C++ could be used to developed rtos or not.
Thanks a lot

C++ does not depend on the os (realtime or not) it depends on the available resources. C is often use instead of C++ because the size of the executable is far smaller.

So there are no decent rtos was developed by c++?

What? Do you ask whether the os is written in C++?

Most current rtos support C++. Once again it has nothing to do with the os itself. It has to do with the available compiler.

Look at this:

To be honest, I don't know. I would expect them to be written in C.

It does look like he is asking if there are real-time OSs implemented in C++.

Yes, it was what I meant.
Sorry for my poor English.

There is no real reason not to write a RTOS in C++. The language itself only has some runtime requirements that would need to be worked around (new, delete, run-time type id, exception handling and the standard libraries).
