如何使用无包的耐用品

void AcquireLicenseForDurable(const char* storeId)
{
    auto async = new XAsyncBlock{};
    async->queue = m_asyncQueue;
    async->callback = [](XAsyncBlock* async)
    {
        XStoreLicenseHandle result = {};

        HRESULT hr = XStoreAcquireLicenseForDurablesResult(
            async,
            &result);

        if (SUCCEEDED(hr))
        {
            bool isValid = XStoreIsLicenseValid(result);
            printf("Is valid license: %s\n", isValid? "yes" : "no");
        }
        else
        {
            printf("Error calling XStoreAcquireLicenseForDurablesResult: 0x%x\n", hr);
        }

        delete async;
    };

    HRESULT hr = XStoreAcquireLicenseForDurablesAsync(
        m_xStoreContext,
        storeId,
        async);

    if (FAILED(hr))
    {
        delete async;
        return;
    }
}
