# SDL\_WaitEvent(3)

Wait indefinitely for the next available event.

## NAME

SDL\_WaitEvent - Wait indefinitely for the next available event.

## HEADER FILE

Defined in SDL3/SDL\_events.h

## SYNOPSIS

```
#include "SDL3/SDL.h"
```

**bool SDL\_WaitEvent(SDL\_Event \*event);**

## DESCRIPTION

If **event** is not NULL, the next event is removed from the queue and stored in the  **SDL\_Event**\
  structure pointed to by **event** .

As this function may implicitly call  **SDL\_PumpEvents** (), you can only call this function in the thread that initialized the video subsystem.

## FUNCTION PARAMETERS

- *event*

  the  **SDL\_Event**\
    structure to be filled in with the next event from the queue, or NULL.

## RETURN VALUE

Returns true on success or false if there was an error while waiting for events; call  **SDL\_GetError** () for more information.

## THREAD SAFETY

This function should only be called on the main thread.

## AVAILABILITY

This function is available since SDL 3.2.0.
