## 実績リストの取得

実行中のタイトルの実績を取得するには、次のように [XblAchievementsGetAchievementsForTitleIdAsync](/reference/live/xsapi-c/achievements_c/functions/xblachievementsgetachievementsfortitleidasync) を呼び出します。

### XblAchievementsGetAchievementsForTitleIdAsync の呼び出し

**C++**

```cpp theme={null}
auto asyncBlock = std::make_unique<XAsyncBlock>();
asyncBlock->queue = queue;
asyncBlock->context = nullptr;
asyncBlock->callback = [](XAsyncBlock* asyncBlock)
{
    std::unique_ptr<XAsyncBlock> asyncBlockPtr{ asyncBlock }; // Take over ownership of XAsyncBlock*.

    XblAchievementsResultHandle resultHandle;
    auto hr = XblAchievementsGetAchievementsForTitleIdResult(asyncBlock, &resultHandle);

    if (SUCCEEDED(hr))
    {
        const XblAchievement* achievements = nullptr;
        size_t achievementsCount = 0;
        hr = XblAchievementsResultGetAchievements(resultHandle, &achievements, &achievementsCount);

        for (size_t i = 0; i < achievementsCount; i++)
        {
            LogToScreen("Achievement %s: %s = %s", 
                achievements[i].id, 
                achievements[i].name,
                (achievements[i].progressState == XblAchievementProgressState::Achieved) ? "Achieved" : "Not achieved");
        }

        XblAchievementsResultCloseHandle(resultHandle); // When you're done with the handle, close it.
        achievements = nullptr; // Clear the array after calling XblAchievementsResultCloseHandle to the pointer to freed memory.
        // Instead, you couldn't close the handle and store it. Then, 
        // if you needed to copy the handle, call XblAchievementsResultDuplicateHandle().
    }
};

HRESULT hr = XblAchievementsGetAchievementsForTitleIdAsync(
    xboxLiveContext,
    xboxUserId,
    titleId,
    achievementType,
    unlockedOnly,
    orderBy,
    skipItems,
    maxItems,
    asyncBlock.get()
);
if (SUCCEEDED(hr))
{
    // The call succeeded, so release the std::unique_ptr ownership of XAsyncBlock* because the callback will take over ownership.
    // If the call fails, std::unique_ptr will keep ownership and delete XAsyncBlock*.
    asyncBlock.release(); 
}
```

## 実績結果の次のページの取得

実績の追加のページが存在する可能性があります。これを確認するには、[XblAchievementsResultHasNext](/reference/live/xsapi-c/achievements_c/functions/xblachievementsresulthasnext) を呼び出してから [XblAchievementsResultGetNextAsync](/reference/live/xsapi-c/achievements_c/functions/xblachievementsresultgetnextasync) を呼び出します。

### XblAchievementsResultHasNext の呼び出し

**Flat C API**

```cpp theme={null}
HRESULT hr = S_OK;
bool hasNext = false;
if (achievementsResult != nullptr)
{
    hr = XblAchievementsResultHasNext(achievementsResult, &hasNext);
}
```

詳細は、[XblAchievementsResultHasNext](/reference/live/xsapi-c/achievements_c/functions/xblachievementsresulthasnext) を参照してください。

### XblAchievementsResultGetNextAsync の呼び出し

実績の次のページを取得するには、次のように [XblAchievementsResultGetNextAsync](/reference/live/xsapi-c/achievements_c/functions/xblachievementsresultgetnextasync) を呼び出します。

**C++**

```cpp theme={null}
auto asyncBlock = std::make_unique<XAsyncBlock>();
asyncBlock->queue = queue;
asyncBlock->context = nullptr;
asyncBlock->callback = [](XAsyncBlock* asyncBlock)
{
    std::unique_ptr<XAsyncBlock> asyncBlockPtr{ asyncBlock }; // Take over ownership of XAsyncBlock*.
    XblAchievementsResultHandle resultHandle;
    auto hr = XblAchievementsResultGetNextResult(asyncBlock, &resultHandle);

    if (SUCCEEDED(hr))
    {
        const XblAchievement* achievements = nullptr;
        size_t achievementsCount = 0;
        hr = XblAchievementsResultGetAchievements(resultHandle, &achievements, &achievementsCount);

        for (size_t i = 0; i < achievementsCount; i++)
        {
            LogToScreen("Achievement %s: %s = %s",
                achievements[i].id,
                achievements[i].name,
                (achievements[i].progressState == XblAchievementProgressState::Achieved) ? "Achieved" : "Not achieved");
        }

        XblAchievementsResultCloseHandle(resultHandle); // When you're done with the handle, close it.
        achievements = nullptr; // Clear the array after calling XblAchievementsResultCloseHandle to the pointer to freed memory.
    }
};

HRESULT hr = XblAchievementsResultGetNextAsync(
    achievementsResult,
    maxItems,
    asyncBlock.get()
);
if (SUCCEEDED(hr))
{
    // The call succeeded, so release the std::unique_ptr ownership of XAsyncBlock* because the callback will take over ownership.
    // If the call fails, std::unique_ptr will keep ownership and delete XAsyncBlock*.
    asyncBlock.release();
}

## 単一の実績の取得

単一の実績を取得するには、次のように [XblAchievementsGetAchievementAsync](/reference/live/xsapi-c/achievements_c/functions/xblachievementsgetachievementasync) を呼び出します。

**Flat C API**

```cpp theme={null}
auto asyncBlock = std::make_unique<XAsyncBlock>();
asyncBlock->queue = queue;
asyncBlock->context = nullptr;
asyncBlock->callback = [](XAsyncBlock* asyncBlock)
{
    std::unique_ptr<XAsyncBlock> asyncBlockPtr{ asyncBlock }; // Take over ownership of XAsyncBlock*.
    XblAchievementsResultHandle resultHandle;
    auto hr = XblAchievementsGetAchievementResult(asyncBlock, &resultHandle);

    if (SUCCEEDED(hr))
    {
        const XblAchievement* achievements = nullptr;
        size_t achievementsCount = 0;
        hr = XblAchievementsResultGetAchievements( resultHandle, &achievements, &achievementsCount );

        // Use the achievements array to read the achievement data.

        XblAchievementsResultCloseHandle(resultHandle); // When you're done with the handle, close it.
        achievements = nullptr; // Clear the array after calling XblAchievementsResultCloseHandle to avoid the pointer to freed memory.
    }
};

HRESULT hr = XblAchievementsGetAchievementAsync(
    xboxLiveContext,
    xboxUserId,
    scid,
    achievementId.c_str(),
    asyncBlock.get()
);
if (SUCCEEDED(hr))
{
    // The call succeeded, so release the std::unique_ptr ownership of XAsyncBlock* because the callback will take over ownership.
    // If the call fails, std::unique_ptr will keep ownership and delete XAsyncBlock*.
    asyncBlock.release();
}
