vga_setlogicalwidth(3)	      Svgalib User Manual	vga_setlogicalwidth(3)

NAME
       vga_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 ac-
       count.  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).

       original	documentation is unknown.

       It is very likely that both are at least	to some	extent are due to Harm

       Occasionally  this  might be wrong. I hereby asked to be	excused	by the
