# SDL_GetPens

Retrieves all pens that are connected to the system.

## Header File

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

## Syntax

```c
SDL_PenID* SDL_GetPens(int *count);

```

## Function Parameters

|               |                                                                                                          |
| ------------- | -------------------------------------------------------------------------------------------------------- |
| **count**     | The number of pens in the array (number of array elements minus 1, i.e., not counting the terminator 0). |

## Return Value

Returns A 0 terminated array of [SDL_PenID](SDL_PenID) values, or NULL on
error. The array must be freed with [SDL_free](SDL_free)(). On a NULL
return, [SDL_GetError](SDL_GetError)() is set.

## Remarks

Yields an array of [SDL_PenID](SDL_PenID) values. These identify and track
pens throughout a session. To track pens across sessions (program restart),
use [SDL_GUID](SDL_GUID) .

## Version

This function is available since SDL 3.0.0.
