#define INCL_WINWINDOWMGR
 
HPS WinGetScreenPS(hwndDesktop)
HWND hwndDesktop;    /* handle of the desktop */
 
The WinGetScreenPS function returns a cached presentation space that can be
used for drawing anywhere on the screen.
 
Parameter    Description
────────────────────────────────────────────────────────────────────────────
 
hwndDesktop  Identifies the desktop window. This parameter can be
             HWND_DESKTOP or the desktop window handle.
 
Return Value
 
The return value is a presentation space, or NULL if an error occurs.
 
Comments
 
When your application finishes using the presentation space, the space
should be released by calling the WinReleasePS function.
 
The WinLockWindowUpdate function should be used to avoid updating the same
part of the screen at the same time.
