#include <graphics.h>
void getpalette(struct palettetype *palette);
 

getpalette fills the palettetype structure pointed to by palette with
information about the current palette's size and colors.
The MAXCOLORS constant and the palettetype structure used by getpalette
are defined in graphics.h as follows:
#define MAXCOLORS  15
 
struct palettetype {
   unsigned char size;
   signed char colors[MAXCOLORS + 1];
};
size gives the number of colors in the palette for the current graphics
driver in the current mode.
colors is an array of size bytes containing the actual raw color numbers
for each entry in the palette.
getpalette cannot be used with the IBM-8514 driver.
