DESCRIPTIONReturns the last video mode number. As video mode numbers start with 1 (0 is for textmode) this allows an application to scan through all possible modes portable with vga_modeinfo(3).
For example the vgatest(6) demo does just that.
#include <vga.h> does include a #define GLASTMODE vga_lastmodenumber().

It is very likely that both are at least to some extent are due to Harm Hanemaayer <[email protected]>.
Occasionally this might be wrong. I hereby asked to be excused by the original author and will happily accept any additions or corrections to this first version of the svgalib manual.
