ScreenInit(D3nfb)

ScreenInit: nfbScreenInit, cfbScreenInit, mfbScreenInit -- initialize screen

Synopsis

#include "nfbProcs.h"

Bool nfbScreenInit (
	ScreenPtr pScreen,
	int xsize,
	int ysize,
	int mmx,
	int mmy);

#include "cfb.h"

Bool cfbScreenInit (
	ScreenPtr pScreen,
	int xsize,
	int ysize,
	int dpix,
	int dpiy
	int width);

#include "mfb.h"

Bool mfbScreenInit (
	ScreenPtr pScreen,
	pointer pbits
	int xsize,
	int ysize,
	int dpix,
	int dpiy
	int width);

Description

nfbScreenInit( ) should be called by a screen's xxxInit( ) function to initialize the NFB screen structure.

Arguments

The arguments are:

pbits: pointer to screen bitmap
pscreen: pointer to the X screen structure
xsize and ysize: screen width and height, in pixels
mmx and mmy: screen width and height, in millimeters
dpix and dpiy: dots per inch
width: width of frame buffer, in pixels

Usage

nfbScreenInit( ) can be used if a simple configuration without a screen prototype is desired; it does not support layers, multiple hardware visuals, multiple hardware colormaps, and cached cursors. Drivers that call nfbScreenInit( ) must call nfbAddVisual(D3nfb) to populate the X screen and VisualRec(D4nfb) structures.

mfbScreenInit( ) and cfbScreenInit( ) use screen prototypes and should be used for adapters that support layers, multiple hardware visuals, multiple hardware colormaps, or cached cursors.

Version applicability

This function is supported for NFB drivers on all releases of SCO OpenServer 5, SVR5, and AIX 5L.
