Re: [ros-bugs] [Bug 949] New: command prompt needs a buffer and scroll bar

[Brandon Turner]

Hello,

I am quite confused about all this and im sure someone can explain it to 
me.  When using ROS cmd on windows, it has a scroll bar but when using 
it on ROS it doesnt.  What is causing this to happen, someone said it in 
IRC a few days ago and i glanced over the code real quick to see if i 
could find out but i couldnt.  Ill look more later but if anyone knows 
could you please explain this to me.

Because console windows are handled by CSRSS and not cmd...

Cmd doesn't know anything about the scrollbar or buffers. This is/should be
implemented in the console stuff in CSRSS. Cmd just uses the console API to
communicate with CSRSS. The reason you can get a scrollbar in Windows but
not in ReactOS is that the Windows CSRSS supports it but ours doesn't (yet).
