# SDL_GetRelativeMouseState

Retrieve the relative state of the mouse.

## Header File

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

## Syntax

```c
SDL_MouseButtonFlags SDL_GetRelativeMouseState(float *x, float *y);
```

## Function Parameters

|         |       |                                                                    |
| ------- | ----- | ------------------------------------------------------------------ |
| float * | **x** | a pointer filled with the last recorded x coordinate of the mouse. |
| float * | **y** | a pointer filled with the last recorded y coordinate of the mouse. |

## Return Value

([SDL_MouseButtonFlags](SDL_MouseButtonFlags)) Returns a 32-bit button
bitmask of the relative button state.

## Remarks

The current button state is returned as a button bitmask, which can be
tested using the `SDL_BUTTON(X)` macros (where `X` is generally 1 for the
left, 2 for middle, 3 for the right button), and `x` and `y` are set to the
mouse deltas since the last call to
[SDL_GetRelativeMouseState](SDL_GetRelativeMouseState)() or since event
initialization. You can pass NULL for either `x` or `y`.

## Version

This function is available since SDL 3.0.0.
