###### (This is the documentation for SDL3, which is under heavy development and the API is changing! [SDL2](https://wiki.libsdl.org/SDL2/) is the current stable version!)
# SDL_BlitSurfaceTiled

Perform a tiled blit to a destination surface, which may be of a different format.

## Header File

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

## Syntax

```c
SDL_bool SDL_BlitSurfaceTiled(SDL_Surface *src, const SDL_Rect *srcrect, SDL_Surface *dst, const SDL_Rect *dstrect);
```

## Function Parameters

|                              |             |                                                                                                                                      |
| ---------------------------- | ----------- | ------------------------------------------------------------------------------------------------------------------------------------ |
| [SDL_Surface](SDL_Surface) * | **src**     | the [SDL_Surface](SDL_Surface) structure to be copied from.                                                                          |
| const [SDL_Rect](SDL_Rect) * | **srcrect** | the [SDL_Rect](SDL_Rect) structure representing the rectangle to be copied, or NULL to copy the entire surface.                      |
| [SDL_Surface](SDL_Surface) * | **dst**     | the [SDL_Surface](SDL_Surface) structure that is the blit target.                                                                    |
| const [SDL_Rect](SDL_Rect) * | **dstrect** | the [SDL_Rect](SDL_Rect) structure representing the target rectangle in the destination surface, or NULL to fill the entire surface. |

## Return Value

([SDL_bool](SDL_bool)) Returns [SDL_TRUE](SDL_TRUE) on success or
[SDL_FALSE](SDL_FALSE) on failure; call [SDL_GetError](SDL_GetError)() for
more information.

## Remarks

The pixels in `srcrect` will be repeated as many times as needed to
completely fill `dstrect`.

## Thread Safety

The same destination surface should not be used from two threads at once.
It is safe to use the same source surface from multiple threads.

## Version

This function is available since SDL 3.0.0.
