fade_out (3alleg4)

#include <allegro.h>

void fade_out(int speed);

Fades gradually from the current palette to a black screen. The speed is from 1 (the slowest) up to 64 (instantaneous).

Note that this function will block your game while the fade is in effect, and it won't work right visually if you are not in an 8 bit color depth resolution.
