NAME

color_map - Global pointer to the color mapping table. Allegro game programming library.

SYNOPSIS

#include <allegro.h>

extern COLOR_MAP *color_map;

DESCRIPTION

Global pointer to the color mapping table. You must allocate your own COLOR_MAP either statically or dynamically and set color_map to it before using any translucent or lit drawing functions in a 256-color video mode! Example:

   color_map = malloc(sizeof(COLOR_MAP));
   if (!color_map)
      abort_on_error("Not enough memory for color map!");
