NAME
ggiSetPalette, ggiGetPalette - Manipulate the palette of a visual
SYNOPSIS
#include <ggi/ggi.h>
int ggiSetPalette(ggi_visual_t vis, int s, int len, const ggi_color *cmap);
int ggiGetPalette(ggi_visual_t vis, int s, int len, ggi_color *cmap);
DESCRIPTION
LibGGI visuals in GT_PALETTE mode map all pixelvalues to the
corresponding ggi_color(3) entry in the visual’s palette.
ggiSetPalette sets a range of palette values of length len, starting at
index number s. The index can be GGI_PALETTE_DONTCARE to indicate that
the palette can be installed anywhere in the CLUT. This allows
optimized use in windowing environments (to minimize color flashing
between windows) and should be used if possible.
ggiGetPalette copies the specified colors (starting from s, for len
colors) from the visual’s palette to the array pointed by cmap.
RETURN VALUE
ggiSetPalette returns the number of the first entry changed. <0
indicate a ggi-error(3).
ggiGetPalette returns 0 for OK, otherwise a ggi-error(3) code. When
called with len=0 this function will not automatically succeed, but the
return code will indicate whether there is a readable CLUT.
