Screen Capture Using C

Hello Everyone,
This may be sort of a newbie question and I realize that it is
probably frontend specifc.  Assuming that there is a desktop
environment I would like to be able to grab a screen scrap using a C
program.  The code that works for OS X is as follows:

PixMap pixMap;
GetQDGlobalsScreenBits((BitMap*)&pixMap);

if anyone knows the answer to this questions or where I could find unix
based c documentation I would greatly appreciate it.
Best, Andrew

Basically, XGetImage.

For details, look in the source code for xwd (part of the X11R6
distribution; http://www.x.org)
