set_palette_range - Sets a specific range of the palette. Allegro game
programming library.
#include <allegro.h>
void set_palette_range(const PALETTE p, int from, int to, int
vsync);
Sets the palette entries between from and to (inclusive: pass 0 and 255 to set
the entire palette). If vsync is set it waits for the vertical retrace,
otherwise it sets the colors immediately. Example:
PALETTE palette;
...
/* Modify the first 16 entries. */
change_first_16_colors(palette);
/* Now update them waiting for vsync. */
set_palette_range(palette, 0, 15, 1);
