Sandeep L R — Tue, 27 Jul 2004 12:47:55 GMT

Please help me in knowing answers to these questions on memory windowing.
1) How do I make use of Memory Windowing for an application
2) Do I need to re compile the application ?
3) Can I run an Non Memory windowing enabled application on System where Memory windoing is enabled ?

Thanks in Advance

Start by reading the man pages of getmemwindow, setmemwindow.

1 By making use of memory windows, an application gets it's seperate shared memory window. You start the program as setmemwindow - "window_no" "program"

The window_no is as defined in /etc/services.window file.

2 You do not need to re-compile the application

3 Yes.

Hi Sandeep,

A slight clarification on Q #3...

IF the non-memory window app has to share a resource - i.e. shared libary or such - with the app running in the memory window then it *must* be running in the same window.
Think of memory windows as little virtual computers, they can only share resources inside their own little domain.

Rgds,
Jeff
