ALLEGRO_GET_EVENT_TYPE(3)                            ALLEGRO_GET_EVENT_TYPE(3)

NAME
       ALLEGRO_GET_EVENT_TYPE - Allegro 5 API

SYNOPSIS

              #include <allegro5/allegro.h>

              #define ALLEGRO_GET_EVENT_TYPE(a, b, c, d)   AL_ID(a, b, c, d)

DESCRIPTION
       Make an event type identifier, which is a 32-bit integer.  Usually, but
       not necessarily, this will be made from four 8-bit character codes, for
       example:

              #define MY_EVENT_TYPE   ALLEGRO_GET_EVENT_TYPE('M','I','N','E')

       IDs less than 1024 are reserved for Allegro or its addons.  Don't use
       anything lower than ALLEGRO_GET_EVENT_TYPE(0, 0, 4, 0).

       You should try to make your IDs unique so they don't clash with any 3rd
       party code you may be using.  Be creative.  Numbering from 1024 is not
       creative.

       If you need multiple identifiers, you could define them like this:

              #define BASE_EVENT   ALLEGRO_GET_EVENT_TYPE('M','I','N','E')
              #define BARK_EVENT   (BASE_EVENT + 0)
              #define MEOW_EVENT   (BASE_EVENT + 1)
              #define SQUAWK_EVENT (BASE_EVENT + 2)

              /* Alternatively */
              enum {
                 BARK_EVENT = ALLEGRO_GET_EVENT_TYPE('M','I','N','E'),
                 MEOW_EVENT,
                 SQUAWK_EVENT
              };
