NAME
gl_getpalettecolor, gl_getpalettecolors, gl_getpalette -
read the color palette
SYNOPSIS
#include <vgagl.h>
void gl_getpalettecolor(int c, int *r, int *g, int *b);
void gl_getpalettecolors(int s, int n, void *dp);
void gl_getpalette(void *dp);
DESCRIPTION
gl_getpalettecolor gets red, green and blue values (in the
range 0 - 63) of color c from the color-lookup-table, and
stores them as integers in the memory locations pointed to
by r, g and b.
gl_getpalettecolors gets RGB values of n colors starting
at s, which are stored as a table of groups of three bytes
each at dp.
gl_getpalette is equivalent to getpalettecolors(0, 256,
dp).
vga_ext_set(3) might change the range of the colors
returned to 0 - 255.
