vga_setlogicalwidth(3) Svgalib User Manual vga_setlogicalwidth(3)NAMEvga_setlogicalwidth - set the logical scanline width
SYNOPSIS
#include <vga.h>
void vga_setlogicalwidth(int l);
DESCRIPTION
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).
