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 run‐
       ning 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.

AUTHOR
       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.
