Subject: Using all colors in a 256-color palette (Overriding system colors)

In OS/2 v1.3 I have used this code, which works well:

	GpiCreateLogColorTable (hpsMemory, LCOL_REALIZABLE, LCOLF_CONSECRGB, 
	                        0L, 256L, (PULONG)&pal[0]);
	GpiRealizeColorTable (hpsMemory);

Since OS/2 v2.0 does not provide the GpiRealizeColorTable function I have tried 
to use the GpiCreatePalette function with the LCOL_OVERRIDE_DEFAULT_COLORS 
option. This option causes GpiCreatePalette to return the error message 
PMERR_INV_COLOR_OPTIONS. This is the v2.0 code:

	hpal = GpiCreatePalette (hab, LCOL_OVERRIDE_DEFAULT_COLORS, 
	                         LCOLF_CONSECRGB, 256L, (PULONG)ppal);
	GpiSelectPalette (hpsMemory, hpal);
	WinRealizePalette (hwnd, hpsMemory, &numcol);

What am I doing wrong ? I am grateful if someone could provide a solution to
this problem. I use an XGA display adapter.
