     configuration

C SPECIFICATION    [Toc]    [Back]

     long getgconfig(long buffer)

     GC_BITS_CMODE  color index	size. zero indicates RGB mode.

     GC_BITS_RED    red	component size.

     GC_BITS_GREEN  green component size.

     GC_BITS_BLUE   blue component size.

     GC_BITS_ALPHA  alpha component size.

     GC_BITS_ZBUFFER    [Toc]    [Back]
		    zbuffer size.

     GC_ZMIN	    minimum depth value	that can be stored in the z-buffer.

     GC_ZMAX	    maximum depth value	that can be stored in the z-buffer.

     GC_BITS_STENCIL    [Toc]    [Back]
		    stencil size.

     GC_BITS_ACBUF  accumulation buffer	size.

     GC_MS_SAMPLES  number of samples in the multisample buffer.

     GC_BITS_MS_ZBUFFER    [Toc]    [Back]
		    multisample	zbuffer	size.

     GC_MS_ZMIN	    minimum depth value	that can be stored in the multisample
		    z-buffer.

     GC_MS_ZMAX	    maximum depth value	that can be stored in the multisample
		    z-buffer.

     GC_BITS_MS_STENCIL    [Toc]    [Back]
		    multisample	stencil	size.

     GC_STEREO	    stereoscopic buffer	state.

     GC_DOUBLE	    display double buffer state.

DESCRIPTION    [Toc]    [Back]

     getgconfig	returns	the size of a buffer or	a state	of some	buffers	in the
     current buffer configuration in the current drawmode.  GC_BITS_ZBUFFER,
     GC_BITS_ACBUF, and	GC_BITS_MS_ZBUFFER will	return a negative size if the
     buffer is signed.
