Downloads and installs the specified store packages.

Syntax

HRESULT XStoreDownloadAndInstallPackagesAsync(  
         const XStoreContextHandle storeContextHandle,  
         const char** storeIds,  
         size_t storeIdsCount,  
         XAsyncBlock* async  
)

Parameters

storeContextHandle _In_
Type: XStoreContextHandle

The store context handle for the user returned by XStoreCreateContext.

storeIds _In_z_count_(storeIdsCount)
Type: char**

List of package identifier strings. A package identifier uniquely identifies a package from the Microsoft store. For more information about package identifiers, see Manage and license downloadable content (DLC).

storeIdsCount _In_
Type: size_t

The number of IDs in storeIds.

async _Inout_
Type: XAsyncBlock*

An XAsyncBlock defining the asynchronous work being done. The XAsyncBlock can be used to poll for the call's status and retrieve call results. See XAsyncBlock for more information.

Return value

Type: HRESULT

HRESULT success or error code.

Remarks

To retrieve the download and install result of this function call XStoreDownloadAndInstallPackagesResult after calling this function. To retrieve the number of items downloaded and installed call XStoreDownloadAndInstallPackagesResultCount after calling this function. The result count function is important as it will allow you to determine the appropriate size of array to pass to the result function.

When this API is called from a running game, then the downloads will be considered high priority and they will go at the beginning of the queue in the order in which they are specified in the storeIds parameter of this API.

The following code snippet shows an example of downloading and installing store packages.

  
void CALLBACK DownloadAndInstallPackagesCallback(XAsyncBlock* asyncBlock)
{
    uint32_t count;

    HRESULT hr = XStoreDownloadAndInstallPackagesResultCount(
        asyncBlock,
        &count);

    if (FAILED(hr))
    {
        printf("Failed retrieve the installing packages count: 0x%x\r\n", hr);
        return;
    }

    printf("Number of updates: %d", count);

    auto packageIdentifiers = new char[count][XPACKAGE_IDENTIFIER_MAX_LENGTH];
    hr = XStoreDownloadAndInstallPackagesResult(
        asyncBlock,
        count,
        &packageIdentifiers[0]);

    if (FAILED(hr))
    {
        delete[] packageIdentifiers;
        printf("Failed retrieve the installing packages results: 0x%x\r\n", hr);
        return;
    }

    for (uint32_t index = 0; index < count; index++)
    {
        printf("packageIdentifier: %s\r\n", packageIdentifiers[index]);
    }

    delete[] packageIdentifiers;
}

void DownloadAndInstallPackages(XStoreContextHandle storeContextHandle, XTaskQueueHandle taskQueueHandle, const char** storeIds, size_t storeIdsCount)
{
    auto asyncBlock = std::make_unique<XAsyncBlock>();
    ZeroMemory(asyncBlock.get(), sizeof(*asyncBlock));
    asyncBlock->queue = taskQueueHandle;
    asyncBlock->context = taskQueueHandle;
    asyncBlock->callback = DownloadAndInstallPackagesCallback;

    HRESULT hr = XStoreDownloadAndInstallPackagesAsync(
        storeContextHandle,
        storeIds,
        storeIdsCount,
        asyncBlock.get());

    if (FAILED(hr))
    {
        printf("Failed to start download and install: 0x%x\r\n", hr);
        return;
    }
}
