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

setallpalette sets the current palette to the values given in the
palettetype structure pointed to by palette.
You can partially (or completely) change the colors in the EGA/VGA
palette with setallpalette.
The MAXCOLORS constant and the palettetype structure used by
setallpalette 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. If an element of colors is -1, the palette
color for that entry is not changed.
The elements in the colors array used by setallpalette can be represented
by symbolic constants which are defined in graphics.h. See Actual Color
Table given here:
Name Value
BLACK0
BLUE 1
GREEN2
CYAN 3
RED  4
MAGENTA    5
BROWN6
LIGHTGRAY  7
DARKGRAY   8
LIGHTBLUE  9
LIGHTGREEN 10
LIGHTCYAN  11
LIGHTRED   12
LIGHTMAGENTA     13
YELLOW     14
WHITE15
EGA_BROWN  20
EGA_DARKGRAY     56
EGA_LIGHTBLUE    57
EGA_LIGHTGREEN   58
EGA_LIGHTCYAN    59
EGA_LIGHTRED     60
EGA_LIGHTMAGENTA 61
EGA_YELLOW 62
EGA_WHITE  63
Changes made to the palette are seen immediately onscreen. Each time a
palette color is changed, all occurrences of that color onscreen change
to the new color value.
Note: Valid colors depend on the current graphics driver and current
graphics mode.
setallpalette cannot be used with the IBM-8514 driver.
