# SDL_GetCurrentDisplayMode

## Header File

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

## Syntax

```c
int SDL_GetCurrentDisplayMode(int displayIndex, SDL_DisplayMode * mode);
```

## Function Parameters

|                                      |                  |                                                                                          |
| ------------------------------------ | ---------------- | ---------------------------------------------------------------------------------------- |
| int                                  | **displayIndex** | the index of the display to query.                                                       |
| [SDL_DisplayMode](SDL_DisplayMode) * | **mode**         | an [SDL_DisplayMode](SDL_DisplayMode) structure filled in with the current display mode. |

## Return Value

(int) Returns 0 on success or a negative error code on failure; call
[SDL_GetError](SDL_GetError)() for more information.

## Remarks

There's a difference between this function and
[SDL_GetDesktopDisplayMode](SDL_GetDesktopDisplayMode)() when SDL runs
fullscreen and has changed the resolution. In that case this function will
return the current display mode, and not the previous native display mode.

## Version

This function is available since SDL 2.0.0.
