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).
