# al\_add\_timer\_count(3alleg5)

Allegro 5 API

## 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.
