#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;

change_first_16_colors(palette);
/* Now update them waiting for vsync. */
set_palette_range(palette, 0, 15, 1);
