vga_setlogicalwidth3vga

Set the logical scanline width

Part of vga_setlogicalwidth(3).

Usage

#include <vga.h>

void vga_setlogicalwidth(int l);

Overview

Set the logical scanline width to l bytes. It must be a multiple of 8. Only changes the VGA register, drawing functions don't take it into account. The logical scan line width is the offset between points above each other in consecutive lines. Note that for some cards and graphics modes a multiple of 8 will not suffice to ensure a proper video timing. You should only set l to multiples of the value returned for that graphics mode by vga_modeinfo(3).
