.TH vga_drawpixel 3 "27 July 1997" "Svgalib (>= 1.2.11)" "Svgalib User Manual"
|
|
.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).

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
