.SH NAME
vga_drawpixel \- draw a pixel on the screen
.SH SYNOPSIS
.B "#include <vga.h>"
.BI "int vga_drawpixel(int " x ", int " y );
.SH DESCRIPTION
Read a pixels value from the screen. This function is very inefficient, you should
consider doing direct screen access instead or use
.BR vga_drawscansegment (3)
to handle more than one pixel.
The color drawn is set with
.BR vga_setcolor (3)
or
.BR vga_setrgbcolor (3)
resp.
The function always returns 0 (on which you should probably not really rely).

.SH 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.
