# SDL_CopyProperties

Copy a group of properties.

## Header File

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

## Syntax

```c
bool SDL_CopyProperties(SDL_PropertiesID src, SDL_PropertiesID dst);
```

## Function Parameters

|                                      |         |                             |
| ------------------------------------ | ------- | --------------------------- |
| [SDL_PropertiesID](SDL_PropertiesID) | **src** | the properties to copy.     |
| [SDL_PropertiesID](SDL_PropertiesID) | **dst** | the destination properties. |

## Return Value

(bool) Returns true on success or false on failure; call
[SDL_GetError](SDL_GetError)() for more information.

## Remarks

Copy all the properties from one group of properties to another, with the
exception of properties requiring cleanup (set using
[SDL_SetPointerPropertyWithCleanup](SDL_SetPointerPropertyWithCleanup)()),
which will not be copied. Any property that already exists on `dst` will be
overwritten.
