This event is unique; it is never created by SDL, but only by the application. The event can be pushed onto the event queue using

SDL_PushEvent (). The contents of the structure members are completely up to the programmer; the only requirement is that '''type''' is a value obtained from SDL_RegisterEvents ().

This struct is available since SDL 3.2.0.
