al_add_timer_count(3)                                    al_add_timer_count(3)

NAME
       al_add_timer_count - Allegro 5 API

SYNOPSIS

              #include <allegro5/allegro.h>

              void al_add_timer_count(ALLEGRO_TIMER *timer, int64_t diff)

DESCRIPTION
       Add diff to the timer's counter value.  This is similar to writing:

              al_set_timer_count(timer, al_get_timer_count(timer) + diff);

       except that the addition is performed atomically, so no ticks will be
       lost.
