Creates a store context for the specified user.

Syntax

HRESULT XStoreCreateContext(  
         const XUserHandle user,  
         XStoreContextHandle* storeContextHandle  
)

Parameters

user _In_opt_
Type: XUserHandle

The user to create the store context for.
This parameter is optional for PC games only: simply pass a nullptr value. On PC the user signed into the Microsoft Store is used automatically and this parameter is ignored. A valid XUser is required for console games.

storeContextHandle _Out_
Type: XStoreContextHandle*

On success contains the created store context.

Return value

Type: HRESULT

HRESULT success or error code.

Remarks

NOTE: On consoles, the XStoreContextHandle created by this function is invalidated after a Suspend or Quick Resume event. To safely handle these conditions we recommend closing a XStoreContextHandle and recreating it whenever the game resumes from a suspended state.

Note

This function isn't safe to call on a time-sensitive thread. For more information, see Time-sensitive threads.

When you are finished with the XStoreContextHandle created by this function, you must close it with XStoreCloseContextHandle. Failure to close the handle will cause a memory leak. The store context is used to identify the user to retrieve information for in a number of the XStore API calls. The following code snippet shows an example of creating a store context.

void CALLBACK GameLicenseChangedCallback(void* context)
{
    UNREFERENCED_PARAMETER(context);
    printf("**** License Changed ****\r\n");
}

void CreateStoreContextHandle(XUserHandle userHandle, XTaskQueueHandle taskQueueHandle)
{
    // As a rule, it would be a good idea to create one of these
    // and keep it alive through the lifetime of the game
    XStoreContextHandle storeContextHandle;

    HRESULT hr = XStoreCreateContext(userHandle, &storeContextHandle);
    if (FAILED(hr))
    {
        printf("Failed creating store context: 0x%x\r\n", hr);
        return;
    }

    XTaskQueueRegistrationToken gameLicenseChangedToken = { 0 };
    hr = XStoreRegisterGameLicenseChanged(
        storeContextHandle,
        taskQueueHandle,
        storeContextHandle,
        GameLicenseChangedCallback,
        &gameLicenseChangedToken);

    if (FAILED(hr))
    {
        printf("Failed register for game license changed callback: 0x%x\r\n", hr);
        XStoreCloseContextHandle(storeContextHandle);
        return;
    }

    //Unregistering the license changed event and closing the XStoreContextHandle would usually go in the cleanup/shutdown sections of your game code. 
    XStoreUnregisterGameLicenseChanged(
        storeContextHandle,
        gameLicenseChangedToken,
        true);

    XStoreCloseContextHandle(storeContextHandle);
}
