# SDL_GetPenType

Retrieves the pen type for a given [SDL_PenID](SDL_PenID).

## Header File

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

## Syntax

```c
SDL_PenSubtype SDL_GetPenType(SDL_PenID instance_id);

```

## Function Parameters

|                     |                   |
| ------------------- | ----------------- |
| **instance_id**     | The pen to query. |

## Return Value

Returns The corresponding pen type (cf. [SDL_PenSubtype](SDL_PenSubtype))
or 0 on error. Note that the pen type does not dictate whether the pen tip
is [SDL_PEN_TIP_INK](SDL_PEN_TIP_INK) or
[SDL_PEN_TIP_ERASER](SDL_PEN_TIP_ERASER); to determine whether a pen is
being used for drawing or in eraser mode, check either the pen tip on
[SDL_EVENT_PEN_DOWN](SDL_EVENT_PEN_DOWN), or the flag
[SDL_PEN_ERASER_MASK](SDL_PEN_ERASER_MASK) in the pen state.

## Version

This function is available since SDL 3.0.0.
