# SDL_GetRenderOutputSize

Get the output size in pixels of a rendering context.

## Header File

Defined in [<SDL3/SDL_render.h>](https://github.com/libsdl-org/SDL/blob/main/include/SDL3/SDL_render.h)

## Syntax

```c
bool SDL_GetRenderOutputSize(SDL_Renderer *renderer, int *w, int *h);
```

## Function Parameters

|                                |              |                                                |
| ------------------------------ | ------------ | ---------------------------------------------- |
| [SDL_Renderer](SDL_Renderer) * | **renderer** | the rendering context.                         |
| int *                          | **w**        | a pointer filled in with the width in pixels.  |
| int *                          | **h**        | a pointer filled in with the height in pixels. |

## Return Value

(bool) Returns true on success or false on failure; call
[SDL_GetError](SDL_GetError)() for more information.

## Remarks

This returns the true output size in pixels, ignoring any render targets or
logical size and presentation.

## Thread Safety

## Version

This function is available since SDL 3.1.3.
