###### (This is the documentation for SDL3, which is under heavy development and the API is changing! [SDL2](https://wiki.libsdl.org/SDL2/) is the current stable version!) # SDL_PushEvent Add an event to the event queue. ## Header File Defined in [SDL_events.h](https://github.com/libsdl-org/SDL/blob/main/include/SDL3/SDL_events.h), but apps should use `#include ` ## Syntax ```c int SDL_PushEvent(SDL_Event *event); ``` ## Function Parameters | | | | ------------- | --------------------------------------------------- | | **event** | the [SDL_Event](SDL_Event) to be added to the queue | ## Return Value Returns 1 on success, 0 if the event was filtered, or a negative error code on failure; call [SDL_GetError](SDL_GetError)() for more information. A common reason for error is the event queue being full. ## Remarks The event queue can actually be used as a two way communication channel. Not only can events be read from the queue, but the user can also push their own events onto it. `event` is a pointer to the event structure you wish to push onto the queue. The event is copied into the queue, and the caller may dispose of the memory pointed to after [SDL_PushEvent](SDL_PushEvent)() returns. Note: Pushing device input events onto the queue doesn't modify the state of the device within SDL. This function is thread-safe, and can be called from other threads safely. Note: Events pushed onto the queue with [SDL_PushEvent](SDL_PushEvent)() get passed through the event filter but events added with [SDL_PeepEvents](SDL_PeepEvents)() do not. For pushing application-specific events, please use [SDL_RegisterEvents](SDL_RegisterEvents)() to get an event type that does not conflict with other code that also wants its own custom event types. ## Version This function is available since SDL 3.0.0. ## Code Examples ```c++ // Default Usage: SDL_Event sdlevent; sdlevent.type = SDL_EVENT_KEY_DOWN; sdlevent.key.keysym.sym = SDLK_1; SDL_PushEvent(&sdlevent); ``` ## See Also * [SDL_PeepEvents](SDL_PeepEvents) * [SDL_PollEvent](SDL_PollEvent) * [SDL_RegisterEvents](SDL_RegisterEvents) ---- [CategoryAPI](CategoryAPI), [CategoryAPIFunction](CategoryAPIFunction), [CategoryEvents](CategoryEvents)
