+.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.
