# XAppCaptureScreenshotStream

스크린샷 스트림을 나타냅니다.

<a id="syntaxSection" />

## 구문

```cpp theme={null}
typedef struct XAppCaptureScreenshotStream {  
} XAppCaptureScreenshotStream  
```

<a id="membersSection" />

### 멤버

이 구조체에는 데이터 멤버가 없습니다.

<a id="remarksSection" />

## 설명

이 구조체를 사용하여 화면 캡처를 수집합니다.

[XAppCaptureTakeScreenshot](/reference/system/xappcapture/functions/xappcapturetakescreenshot)을 호출하여 게임의 스크린샷을 촬영할 수 있습니다.

`XAppCaptureTakeScreenshot`은 하나 이상의 로컬 ID를 반환하며, 이를 [XAppCaptureOpenScreenshotStream](/reference/system/xappcapture/functions/xappcaptureopenscreenshotstream) 호출에 전달하여 화면 캡처를 검색하는 데 사용할 수 있습니다. HDR 화면의 스크린샷을 촬영하면 두 개의 로컬 ID(하나는 SDR 버전용, 하나는 HDR 버전용)를 받게 됩니다.

`XAppCaptureOpenScreenshotStream`은 `XAppCaptureScreenshotStream` 개체에 대한 핸들을 반환합니다. 이 핸들을 [XAppCaptureReadScreenshotStream](/reference/system/xappcapture/functions/xappcapturereadscreenshotstream) 호출에 전달하여 스트림의 내용을 읽을 수 있습니다.

완료되면 [XAppCaptureCloseScreenshotStream](/reference/system/xappcapture/functions/xappcaptureclosescreenshotstream)을 호출하여 핸들을 닫습니다.

## 예제

다음 코드 예제는 스크린샷 스트림의 내용을 로컬 파일에 쓰는 방법을 보여 줍니다.

```cpp theme={null}
void WriteScreenshotStreamToFile(_In_ const char* screenshotLocalId, _In_ XAppCaptureScreenshotFormatFlag screenshotFormat, _In_ const char* filePath)
{
    const int MAX_DATA = 1024;
    XAppCaptureScreenshotStreamHandle handle = nullptr;
    BYTE buffer[MAX_DATA];
    HANDLE file = INVALID_HANDLE_VALUE;
    UINT64 totalBytesRead = 0;
    UINT64 totalBytesToRead = 0;

    if (FAILED_LOG(XAppCaptureOpenScreenshotStream(screenshotLocalId, screenshotFormat, &handle, &totalBytesToRead)))
    {
        return;
    }

    appLog.AddLog("%I64d bytes returned\n", totalBytesToRead);

    file = CreateFileA(filePath, GENERIC_READ | GENERIC_WRITE, 0, 0, CREATE_ALWAYS, FILE_ATTRIBUTE_NORMAL, 0);
    if (file == INVALID_HANDLE_VALUE)
    {
        appLog.AddLog("Could not create %s\n", filePath);
        goto Cleanup;
    }

    while (totalBytesRead < totalBytesToRead)
    {
        uint32_t bytesRead = 0;
        DWORD bytesWritten = 0;

        if (FAILED_LOG(XAppCaptureReadScreenshotStream(handle, totalBytesRead, sizeof(buffer), buffer, &bytesRead)))
        {
            goto Cleanup;
        }

        BOOL result = WriteFile(file, buffer, bytesRead, &bytesWritten, NULL );
        if (!result)
        {
            appLog.AddLog("Failed to write to %s\n", filePath);
            goto Cleanup;
        }

        totalBytesRead += bytesRead;
    }

Cleanup:
    if (handle != nullptr)
    {
        FAILED_LOG(XAppCaptureCloseScreenshotStream(handle));
    }
    if (file != INVALID_HANDLE_VALUE)
    {
        CloseHandle(file);
    }
    appLog.AddLog("Wrote out %I64d bytes to %s\n", totalBytesRead, filePath);

}
