getpalette

Gets information about the current palette.

Defined in header <graphics.h>

Syntax

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

Portability

Remarks

getpalette fills the palettetype structure pointed to by palette with information about the current palette's size and colors.

getpalette are defined in graphics.h as follows:

ttdefine 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.

Return value

None.
