Tried to fix this so it's more understandable. If I've messed up your
meaning, say something.
I would like to capture the primary display and [draw it] into [a]
window. How can i access [the] memory area of the display? My
application should render the primary display continously by only
updating the changes in the screen.
This sounds like you're trying to reinvent x11vnc or vino or KDE Desktop
Sharing. I think you should be more specific about the problem you're
trying to solve.
The intention is to [draw] the primary display in [an] application
window on the same machine.
Huh? This doesn't make a lot of sense. Does this machine have multiple
Displays? Is it dual-head? Is it using Xinerama? You need to be more
specific about the X config and the hardware you're using. It sounds
like you have multiple monitors, maybe in separate Screens, maybe not,
and you want the contents of one monitor displayed on another monitor,
potentially scaled down. This could get tricky and might be slow. ISTR
something on comp.os.linux.* about someone who wanted to do something
similar to this using a VNC-analogue, but I can't find the message and
its eventual solution in my notes. Oh well, HTH anyway,
