|
|
.SH NAME
|
|
gl_setcontextvga \- set the context to the physical screen
|
|
|
|
.SH SYNOPSIS
|
|
.B #include <vgagl.h>
|
|
|
|
.BI "int gl_setcontextvga(int " mode );
|
|
|
|
.SH DESCRIPTION
|
|
Set the graphics context to the physical screen of a
|
|
vga mode (as defined in
|
|
.BR vga_setmode (3)).
|
|
The mode must be set with
|
|
.BR vga_setmode (3)
|
|
prior to using any of the drawing functions.
|
|
.B vgagl
|
|
does not take care of that.
|
|
|
|
The function returns 0 for success and non-zero if the mode is not supported by the
|
|
hardware.
|
|
|
|
The only thing you can do with a planar (mode X-like)
|
|
256 color mode is aligned
|
|
.BR gl_putbox ,
|
|
and use it as a target for
|
|
.BR gl_copyscreen .
|
|
|
|
In all of the svga modes this program makes a description of the vga
|
|
mode available to the vgagl functions. The 256 color svgamodes are
|
|
handled properly by this program.
