#include <allegro5/allegro.h>

void al_resume_timer(ALLEGRO_TIMER *timer)

Resume the timer specified. From then, the timer’s counter will increment at a constant rate, and it will begin generating events. Resuming a timer that is already started does nothing. Resuming a stopped timer will not reset the timer’s counter (unlike al_start_timer).
