         XAsyncBlock* async  
)

The service ticket associated with the purchase.

publisherUserId _In_z_
Type: char*

A string containing the publisher user ID.

async _Inout_
Type: XAsyncBlock*

Return value

Type: HRESULT

Remarks

To retrieve the customer's purchase ID as well as the execution result of this function call XStoreGetUserPurchaseIdResult after calling this function. To retrieve the size of the customer's purchase ID call XStoreGetUSerPurchaseIdResultSize after calling this function. Knowing the result size will help you read the result more efficiently.

The following code snippet shows an example of retrieving a customer purchase ID.

void CALLBACK GetUserPurchaseIdCallback(XAsyncBlock* asyncBlock)
{
    size_t size;
    HRESULT hr = XStoreGetUserPurchaseIdResultSize(
        asyncBlock,
        &size);

    if (FAILED(hr))
    {
        printf("Failed retrieve the user purchase ID size: 0x%x\r\n", hr);
        return;
    }

    char* result = new char[size];
    hr = XStoreGetUserPurchaseIdResult(
        asyncBlock,
        size,
        result);

    if (FAILED(hr))
    {
        printf("Failed retrieve the user purchase ID result: 0x%x\r\n", hr);
        delete[] result;
        return;
    }

    printf("result: %s\r\n", result);

    delete[] result;
}

void GetUserPurchaseId(XStoreContextHandle storeContextHandle, XTaskQueueHandle taskQueueHandle, const char* serviceTicket, const char* publisherUserId)
{
    auto asyncBlock = std::make_unique<XAsyncBlock>();
    ZeroMemory(asyncBlock.get(), sizeof(*asyncBlock));
    asyncBlock->queue = taskQueueHandle;

    asyncBlock->callback = GetUserPurchaseIdCallback;

    HRESULT hr = XStoreGetUserPurchaseIdAsync(
        storeContextHandle,
        serviceTicket,
        publisherUserId,
        asyncBlock.get());

    if (FAILED(hr))
    {
        printf("Failed to get user purchase ID: 0x%x\r\n", hr);
        return;
    }
}
