# ALLEGRO\_EVENT\_SOURCE(3alleg5)

Allegro 5 API

## NAME

ALLEGRO\_EVENT\_SOURCE - Allegro 5 API

## SYNOPSIS

-

  ```
  #include <allegro5/allegro.h>
  typedef struct ALLEGRO_EVENT_SOURCE ALLEGRO_EVENT_SOURCE;
  ```

## DESCRIPTION

An event source is any object which can generate events. For example, an ALLEGRO\_DISPLAY can generate events, and you can get the ALLEGRO\_EVENT\_SOURCE pointer from an ALLEGRO\_DISPLAY with al\_get\_display\_event\_source(3alleg5).

You may create your own “user” event sources that emit custom events.
