NAME

6       vga_setlogicalwidth - set the logical scanline width

SYNOPSIS

9       #include <vga.h>
10
11       void vga_setlogicalwidth(int l);

DESCRIPTION

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