vga_addmode(3)		      Svgalib User Manual		vga_addmode(3)

NAME
       vga_addmode - add a mode	to svgalib modes list

SYNOPSIS
       #include	<vga.h>

       int  vga_addmode(int  width,  int height, int num_cols, int offset, int
       bytesperpixel )

DESCRIPTION
       Adds a mode to the list of modes, with the given	parameters.  The func-
       tion returns the	mode number. If	such a	mode  already  exists  on  the
       list, its number	is returned, and no mode is added.

NOTE
       Adding  a mode to the list is not enough	in order to use	it. There must
       also be a timing	line that fits that mode. This can be added either  as
       a modeline in the config	file, or with one of the functions vga_addtim-
       ing(3) and vga_guesstiming(3).
