# XStoreCanAcquireLicenseForPackageAsync

> XStoreCanAcquireLicenseForPackageAsync

# XStoreCanAcquireLicenseForPackageAsync

Retrieves a preview license for DLC (Durable with package).
This API allows the game to see if the Durable's package is licensable, but without actually acquiring the license.

## Syntax

```cpp theme={null}
HRESULT XStoreCanAcquireLicenseForPackageAsync(  
         const XStoreContextHandle storeContextHandle,  
         const char* packageIdentifier,  
         XAsyncBlock* async  
)  
```

### Parameters

*storeContextHandle*   \_In\_\
Type: XStoreContextHandle

The store context handle for the user returned by [XStoreCreateContext](/reference/system/xstore/functions/xstorecreatecontext).

*packageIdentifier*   \_In\_z\_\
Type: char\*

A string that uniquely identifies a store package. For more information about package identifiers, see [Manage and license downloadable content (DLC)](/publishing/xstore-commerce/xstore-dlc).

*async*   \_Inout\_\
Type: [XAsyncBlock\*](/reference/system/xasync/structs/xasyncblock)

An [XAsyncBlock](/reference/system/xasync/structs/xasyncblock) defining the asynchronous work being done.
The [XAsyncBlock](/reference/system/xasync/structs/xasyncblock) can be used to poll for the call's status and retrieve call results.
See [XAsyncBlock](/reference/system/xasync/structs/xasyncblock) for more information.

### Return value

Type: HRESULT

HRESULT success or error code.

## Remarks

To retrieve the preview license and the execution result of this function call [XStoreCanAcquireLicenseForPackageResult](/reference/system/xstore/functions/xstorecanacquirelicenseforpackageresult) after calling this function.
This function requires an online connection and only checks whether a package's license can be acquired.
To acquire a license for a package, call [XStoreAcquireLicenseForPackageAsync](/reference/system/xstore/functions/xstoreacquirelicenseforpackageasync).

This code snippet shows an example of using the following APIs:

* [XStoreCanAcquireLicenseForPackageAsync](/reference/system/xstore/functions/xstorecanacquirelicenseforpackageasync)
* [XStoreCanAcquireLicenseForPackageResult](/reference/system/xstore/functions/xstorecanacquirelicenseforpackageresult)

```cpp theme={null}
void CALLBACK CanAcquireLicenseForPackageCallback(XAsyncBlock* asyncBlock)
{
    XStoreCanAcquireLicenseResult canAcquireLicenseResult{};

    HRESULT hr = XStoreCanAcquireLicenseForPackageResult(
        asyncBlock,
        &canAcquireLicenseResult);

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

    printf("status       : %d\r\n", canAcquireLicenseResult.status);
    printf("licensableSku: %s\r\n", canAcquireLicenseResult.licensableSku);
}

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

    HRESULT hr = XStoreCanAcquireLicenseForPackageAsync(
        storeContextHandle,
        packageIdentifier,
        asyncBlock.get());

    if (FAILED(hr))
    {
        printf("Failed to get preview license for package: 0x%x\r\n", hr);
        return;
    }
}


```
