## Syntax

```c
SDL_bool SDL_HasRectIntersection(const SDL_Rect * A,
                             const SDL_Rect * B);

```

|           |                                                                     |
| --------- | ------------------------------------------------------------------- |
| **A**     | an [SDL_Rect](SDL_Rect) structure representing the first rectangle  |
| **B**     | an [SDL_Rect](SDL_Rect) structure representing the second rectangle |

## Return Value
