This is from a working program:

	
	
#include <Color.h>


typedef	struct	ScreenWorld
{
	int			bitDepth;
	int			inColor;
	int			hPix;
	int			vPix;
}ScreenWorld;



void	GetScreenInfo(ScreenWorld *theScreen);


void	GetScreenInfo(theScreen)
ScreenWorld *theScreen;
{
 GDHandle	curGD;
 Rect		tempRect;

	curGD = GetGDevice();
	tempRect = (**(**curGD).gdPMap).bounds;
	theScreen->hPix =  tempRect.right - tempRect.left;
	theScreen->vPix =  tempRect.bottom - tempRect.top;
	theScreen->bitDepth = (**(**curGD).gdPMap).pixelSize;
	theScreen->inColor = (BitTst( &( (**curGD).gdFlags ), 15));
}
