# IDStorageQueueX::EnqueueSignal

Enqueues a fence write.

## Syntax

```cpp theme={null}
void EnqueueSignal(  
         ID3D12Fence *fence,  
         UINT64 value  
)  
```

### Parameters

*fence*\
Type: ID3D12Fence

An `ID3D12Fence` to enqueue.

*value*\
Type: UINT64

The value to write to the fence.

### Return value

Type: void

## Remarks

The fence is signaled when all requests enqueued before the fence complete.

A title thread can wait for the fence or poll the fence. The GPU can also poll
the fence.

If the `EnqueueSignal` method fills half of the queue's capacity since the last
submission, it triggers an automatic submission as part of the `EnqueueSignal`
call.

In most cases, this method simply does a memory write to the queue, thus takes
very little CPU time to complete. However, if automatic submission is triggered,
it takes significantly more CPU time, including a kernel mode transition and
processing all of the previously submitted requests in the caller thread.

If automatic submission is not desirable, games are recommended to use a queue
with large enough capacity and call [Submit](/reference/system/dstorage/interfaces/IDStorageQueueX/methods/idstoragequeuex_submit) manually
when appropriate.

"EnqueueStatus/EnqueueSignal/EnqueueSetEvent" sections in [DirectStorage
