SYNOPSIS

C]
#include <allegro5/allegro.h>

typedef struct ALLEGRO_USER_EVENT ALLEGRO_USER_EVENT; ]

DESCRIPTION

An event structure that can be emitted by user event sources. These are the public fields:
[bu] ALLEGRO_EVENT_SOURCE *source;
[bu] intptr_t data1;
[bu] intptr_t data2;
[bu] intptr_t data3;
[bu] intptr_t data4;
Like all other event types this structure is a part of the ALLEGRO_EVENT union. To access the fields in an ALLEGRO_EVENT variable C]ev], you would use:
[bu] ev.user.source
[bu] ev.user.data1
[bu] ev.user.data2
[bu] ev.user.data3
[bu] ev.user.data4
To create a new user event you would do this:
C]
ALLEGRO_EVENT_SOURCE my_event_source;
ALLEGRO_EVENT my_event;
float some_var;

al_init_user_event_source(&my_event_source);

my_event.user.type = ALLEGRO_GET_EVENT_TYPE([aq]M[aq],[aq]I[aq],[aq]N[aq],[aq]E[aq]); my_event.user.data1 = 1; my_event.user.data2 = &some_var;

al_emit_user_event(&my_event_source, &my_event, NULL); ]

Event type identifiers for user events are assigned by the user. Please see the documentation for ALLEGRO_GET_EVENT_TYPE(3) for the rules you should follow when assigning identifiers.
