Who would have thought that even simple things could be so hard with 3DGS. After two hours of basic trial and error i came up with this:

Code:
#include <acknex.h>  // Pure-Mode
#include <default.c> // Standard-Keys
#include <windows.h> // Windows-API-Calls

typedef struct _devicemode {
  DWORD dmBitsPerPel;
  DWORD dmPelsWidth;
  DWORD dmPelsHeight;
  DWORD dmDisplayFlags;
  DWORD dmDisplayFrequency;
} SCRMODE;

var rvalue = 0;
var xvalue = 0;

PANEL* pan_results = 
{
	pos_x = 0;
	pos_y = 0;
	layer = 1;
	flags = OVERLAY | VISIBLE;
	digits(0, 40, 4, *, 1, rvalue);
	digits(0, 60, 4, *, 1, xvalue);
}

function getscreenres()
{
	SCRMODE* resolution;	
	rvalue = EnumDisplaySettings(NULL, 1, resolution);
}

void main() 
{
	video_mode = 8;
	video_screen = 2;
	level_load("title.wmb");
	wait(1);
	getscreenres();	
}


At this point I had encountered about three to four dozen SED-Crashes while trying to use printf for small debug outputs.

As far as my code goes right now it seems to work. rvalue returns 1 or 0, depending on how high i set the second parameter of EnumDisplaySettings. Now i wanted to use xvalue to fetch the width of the returned resolution inside my resolution pointer.

This is what I tried:

Version 1:
Code:
function getscreenres()
{
	SCRMODE* resolution;	
	rvalue = EnumDisplaySettings(NULL, 1, resolution);
	xvalue = resolution->dmPelsWidth;
}


Version 2:
Code:
function getscreenres()
{
	SCRMODE* resolution;	
	rvalue = EnumDisplaySettings(NULL, 1, resolution);
	xvalue = resolution.dmPelsWidth;
}


Both ended up in Error E1513 "Crash in getscreenres". Any ideas how that could be fixed? I think I'm referencing wrong, but according to the manual it should work.

Again, any help is appreciated.
