SDL_UserEvent is in the user member of the structure SDL_Event. This event is unique, it is never created by SDL but only by the user. The event can be pushed onto the event queue using SDL_PushEvent. The contents of the structure members or completely up to the programmer, the only requirement is that type is a value from SDL_USEREVENT to SDL_NUMEVENTS-1 (inclusive).

SDL_Event event;

event.type = SDL_USEREVENT;
event.user.code = my_event_code;
event.user.data1 = significant_data;
event.user.data2 = 0;
SDL_PushEvent(&event);
