# XUserGetGamerPictureResultSize

[XUserGetGamerPictureAsync](/reference/system/xuser/functions/xusergetgamerpictureasync)가 반환하는 게이머 사진을 가져오기 위해 [XUserGetGamerPictureResult](/reference/system/xuser/functions/xusergetgamerpictureresult)에서 필요한 버퍼 크기를 반환합니다.

## 구문

```cpp theme={null}
HRESULT XUserGetGamerPictureResultSize(  
         XAsyncBlock* async,  
         size_t* bufferSize  
)  
```

### 매개변수

*async*   \_Inout\_\
형식: [XAsyncBlock\*](/reference/system/xasync/structs/xasyncblock)

[XUserGetGamerPictureAsync](/reference/system/xuser/functions/xusergetgamerpictureasync)에 전달된 비동기 블록입니다.

*bufferSize*   \_Out\_\
형식: size\_t\*

버퍼 크기 요구 사항을 포함합니다.

### 반환값

형식: HRESULT

HRESULT 성공 또는 오류 코드입니다.\
오류 코드 목록은 [Error Codes](/reference/errorcodes)를 참조하십시오.

## 설명

특정 사용자의 게이머 사진을 비동기적으로 가져오려면 [XUserGetGamerPictureAsync](/reference/system/xuser/functions/xusergetgamerpictureasync)를 호출합니다.

[XUserGetGamerPictureAsync](/reference/system/xuser/functions/xusergetgamerpictureasync) 호출의 결과를 가져오려면 [XUserGetGamerPictureResult](/reference/system/xuser/functions/xusergetgamerpictureresult)를 호출합니다.

다음 예제는 게이머 사진을 로드하는 방법을 보여줍니다.
