# CMBufferQueueGetTotalSize(_:)

Gets the total size of all sample buffers of a buffer queue.

## Declaration

```swift
func CMBufferQueueGetTotalSize(_ queue: CMBufferQueue) -> Int
```

## Discussion

Discussion The total size of the CMBufferQueue is the sum of all the individual buffer sizes, as reported by the getTotalSize callback (provided to CMBufferQueueCreate(allocator:capacity:callbacks:queueOut:)). This function returns 0 if there are no buffers in the queue.
