Provides and initializes a XGameSave Provider handle.

Syntax

HRESULT XGameSaveInitializeProvider(  
         XUserHandle requestingUser,  
         const char* configurationId,  
         bool syncOnDemand,  
         XGameSaveProviderHandle* provider  
)

Parameters

requestingUser _In_
Type: XUserHandle

Handle to an Xbox Live user.

configurationId _In_z_
Type: char*

Service configuration ID (SCID).

syncOnDemand _In_
Type: bool

When true, syncOnDemand only downloads data from the service if needed. Does not work if device is offline. Setting to true may cause sync progress UI to be shown.

provider _Outptr_result_nullonfailure_
Type: XGameSaveProviderHandle*

A handle to the XGameSave Provider to be created.

Return value

Type: HRESULT

Function result.

Common errors

E_GS_USER_CANCELED
E_GS_USER_NOT_REGISTERED_IN_SERVICE
E_GS_NO_ACCESS
E_GS_NO_SERVICE_CONFIGURATION

The most commonly returned errors are E_OUTOFMEMORY, E_INVALIDARG,

Remarks

Note

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

This function must be called successfully before other XGameSave APIs are used. This function should not be called on the game's UI thread as it can block and potentially show UI to the user as it synchronizes the player's game saves. If you need to intialize this from the UI thread, consider calling XGameSaveInitializeProviderAsync.

Note

The XGameSave API requires your title to have its title ID and service configuration ID (SCID) properly configured in order to work. For more information about these required IDs, see Setting Up Sandboxes for Xbox Live Development. Your game must be enabled for Xbox Live in Partner Center.

If you do not configure your SCID and Title ID properly, your XSaveGame API calls will fail with the following error code:

E_GS_NO_ACCESS - 0x80830002 - The operation failed because the title does not have access to the container storage spaces.

When this API is called with syncOnDemand set to true it behaves the same from a caller perspective but it does cause some behavior differences in the rest of the API. The SyncOnDemand XGameSaveProvider will only download data from the service if needed but this also comes with the drawback that any container operation might be delayed in this case and this delay may cause some UX to be shown to the user for the sync progress. Using any of the following methods can force a sync:

Another drawback would be that if the device is offline or has connectivity issues then accessing the container is impossible. There is an asynchronous version of this function called XGameSaveInitializeProviderAsync

// SYNC Init - should not be called on time sensitive thread 
//             as this will block until the operation is complete 
void Sample::_InitializeSync() 
{ 
    HRESULT hr; 
    XGameSaveProviderHandle provider = nullptr; 
    hr = XGameSaveInitializeProvider(this->_xalUser, "SERVICE_CONFIG_ID-DEADBEEF0123", false, &provider); 
    if (SUCCEEDED(hr)) 
    { 
        this->_provider = provider; 
    } 
    else 
    { 
        _HandleInitializeErrors(this->_xalUser, hr); 
    } 
} 
 
// handle initialization errors  
void Sample::_HandleInitializeErrors(XUserHandle userContext, HRESULT hr) 
{ 
    switch (hr) 
    { 
    case E_GS_USER_CANCELED: 
        printf("User %p canceled initialization hr=0x%08x\n", userContext, hr); 
        break; 
    case E_GS_USER_NOT_REGISTERED_IN_SERVICE: 
        printf("User %p has no service registration\n", userContext); 
        break; 
    /* NOTE These should only be seen if there is a configuration issue */ 
    case E_GS_NO_ACCESS: 
    case E_GS_NO_SERVICE_CONFIGURATION: 
        printf("Problems with Service Configuration registration\n"); 
        break; 
    case S_OK: 
        break; 
    default: 
        printf("Unknown initialization error for User %p hr=0x%08X\n", userContext, hr); 
    } 
}

Games cannot mix the usage of XGameSaveFiles with the usage of XGameSave. Games much choose which cloud save system they want to use. If the game is using XGameSaveFiles and later calls XGameSaveInitializeProvider, it will error out with E_GS_PROVIDER_MISMATCH. Equally, if the game was using XGameSave and later calls XGameSaveFilesGetFolderWithUiAsync, that will also error out with E_GS_PROVIDER_MISMATCH.
