# PFMultiplayerFinishProcessingMatchmakingStateChanges

> Returns the array of PlayFab Multiplayer matchmaking state changes previously retrieved for processing, releasing resources back to the library.

Returns an array of matchmaking state changes that were being processed.

## Syntax

```cpp theme={null}
HRESULT PFMultiplayerFinishProcessingMatchmakingStateChanges(  
    PFMultiplayerHandle handle,  
    uint32_t stateChangeCount,  
    const PFMatchmakingStateChange* const* stateChanges  
)  
```

### Parameters

**`handle`**   PFMultiplayerHandle

The handle of the PFMultiplayer API instance.

**`stateChangeCount`**   uint32\_t

The number of changes, provided in the list specified by `stateChanges`, previously returned by [PFMultiplayerStartProcessingMatchmakingStateChanges()](/services/playfab/multiplayer/lobby/playfabmultiplayerreference-cpp/pfmatchmaking/functions/pfmultiplayerstartprocessingmatchmakingstatechanges) that have now been handled by the title.

**`stateChanges`**   PFMatchmakingStateChange\* const\*\
*input array of size `stateChangeCount`*

The array of changes previously returned by [PFMultiplayerStartProcessingMatchmakingStateChanges()](/services/playfab/multiplayer/lobby/playfabmultiplayerreference-cpp/pfmatchmaking/functions/pfmultiplayerstartprocessingmatchmakingstatechanges) that have now been handled by the title.

### Return value

Type: HRESULT

`S_OK` if the call succeeded or an error code otherwise. The human-readable form of the error code can be retrieved via [PFMultiplayerGetErrorMessage()](/services/playfab/multiplayer/lobby/playfabmultiplayerreference-cpp/pfmultiplayer/functions/pfmultiplayergeterrormessage).

## Remarks

This method informs the Matchmaking library that the state changes reported by a previous call to [PFMultiplayerStartProcessingMatchmakingStateChanges()](/services/playfab/multiplayer/lobby/playfabmultiplayerreference-cpp/pfmatchmaking/functions/pfmultiplayerstartprocessingmatchmakingstatechanges) have now been handled by the title, so their associated resources can be reclaimed. You may call PFMultiplayerFinishProcessingMatchmakingStateChanges() with any number of state changes. Each state change returned by PFMultiplayerStartProcessingMatchmakingStateChanges() must be returned to PFMultiplayerFinishProcessingMatchmakingStateChanges() exactly once, but may be returned out of order and may be interleaved with state changes from other calls to PFMultiplayerStartProcessingMatchmakingStateChanges(). <br /><br /> Any resources associated with a specific state change are guaranteed to stay valid until the state change is returned to PFMultiplayerFinishProcessingMatchmakingStateChanges().   <br /><br /> For best results, you should minimize the time you spend handling state changes before calling PFMultiplayerFinishProcessingMatchmakingStateChanges().
