```cpp theme={null}
HRESULT PFEventPipelineCreateTelemetryPipelineHandleWithKey(  
    PFEventPipelineTelemetryKeyConfig* eventPipelineTelemetryKeyConfig,  
    XTaskQueueHandle queue,  
    PFEventPipelineBatchUploadSucceededEventHandler* eventPipelineBatchUploadedEventHandler,  
    PFEventPipelineBatchUploadFailedEventHandler* eventPipelineBatchFailedEventHandler,  
    void* handlerContext,  
    PFEventPipelineHandle* eventPipelineHandle  
)  
```

### Parameters

Optional handler that will be invoked when a batch of events is uploaded.

**`eventPipelineBatchFailedEventHandler`**   PFEventPipelineBatchUploadFailedEventHandler\*<br />*optional*

Optional handler that will be invoked when uploading a batch of events fails.

**`handlerContext`**   void\*<br />*optional*

Optional pointer to data used by the event handlers.

**`eventPipelineHandle`**   PFEventPipelineHandle\*<br />*output*
