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 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).
