al_start_timer - Allegro 5 API

#include <allegro5/allegro.h>
void al_start_timer(ALLEGRO_TIMER *timer)
    

Start the timer specified. From then, the timer's counter will increment at a constant rate, and it will begin generating events. Starting a timer that is already started does nothing. Starting a timer that was stopped will reset the timer's counter, effectively restarting the timer from the beginning.
