# SDL_DXGIGetOutputInfo

Get the DXGI Adapter and Output indices for the specified display index.

## Header File

Defined in [SDL_system.h](https://github.com/libsdl-org/SDL/blob/SDL2/include/SDL_system.h)

## Syntax

```c
SDL_bool SDL_DXGIGetOutputInfo( int displayIndex, int *adapterIndex, int *outputIndex );

```

## Function Parameters

|                      |                                                  |
| -------------------- | ------------------------------------------------ |
| **displayIndex**     | the display index for which to get both indices  |
| **adapterIndex**     | a pointer to be filled in with the adapter index |
| **outputIndex**      | a pointer to be filled in with the output index  |

## Return Value

Returns [SDL_TRUE](SDL_TRUE) on success or [SDL_FALSE](SDL_FALSE) on
failure; call [SDL_GetError](SDL_GetError)() for more information.

## Remarks

The DXGI Adapter and Output indices can be passed to `EnumAdapters` and
`EnumOutputs` respectively to get the objects required to create a DX10 or
DX11 device and swap chain.

Before SDL 2.0.4 this function did not return a value. Since SDL 2.0.4 it
returns an [SDL_bool](SDL_bool).

## Version

This function is available since SDL 2.0.2.
