vga_oktowrite(3) Svgalib User Manual vga_oktowrite(3)NAME
vga_oktowrite - indicates whether the program has direct access to the SVGA
SYNOPSIS
#include <vga.h>
int vga_oktowrite(void);
DESCRIPTION
Indicates whether the program is in the console currently visible on the screen, that is, whether it is OK to write to video memory (if
running in the background has been allowed with the function above). Note that this is not entirely safe, since a console switch interrupt
may occur during a video operation. It is best to avoid this function.
Usually your program will be suspended when it has no access to the screen but see vga_runinbackground(3) for an alternative.

This manual page was edited by Michael Weller <eowmob@exp-math.uni-essen.de>. The exact source of the referenced function as well as of the
original documentation is unknown.
It is very likely that both are at least to some extent are due to Harm Hanemaayer <H.Hanemaayer@inter.nl.net>.
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.
