Show Windows Contents While Dragging

Is there an Windows API I can use to return the value
of Show Windows Contents While Dragging?
On NT, this option is set by the user via Settings /
Control Panel / Display / Plus! / Visual Settings .

I hope the following helps:
The registry key HKEY_USERS\.Default\Control Panel\desktop\DragFullWindows
contains '1' if enabled, '0' if disabled - if that is what you meant.
(Tested with Win95, but i am quite sure that it's the same with NT)
If you think this has answered your question, feel free to let me know that i should post an
answer :) :) :)

Yes, that location in the registry is very helpful.
Now I just need a way to obtain that value programatically.
Can you use GetProfileInt() somehow to retrieve the value?

BOOL SystemParametersInfo( UINT uiAction, // system parameter to query or set
UINT uiParam, // depends on action to be taken
PVOID pvParam, // depends on action to be taken
UINT fWinIni // user profile update flag);

SPI_GETDRAGFULLWINDOWS Determines whether dragging of full windows is enabled. The pvParam parameter must point to a BOOL variable that receives TRUE if enabled, or FALSE otherwise.
Windows 95: This flag is supported only if Windows Plus! is installed. See SPI_GETWINDOWSEXTENSION.
