set_palette_range(3)            Allegro manual            set_palette_range(3)

NAME
       set_palette_range - Sets a specific range of the palette. Allegro game
       programming library.

SYNOPSIS
       #include <allegro.h>

       void set_palette_range(const PALETTE p, int from, int to, int vsync);

DESCRIPTION
       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);
