# withBuffers

## Declaration

```occ
static IOStream *withBuffers(
 OSArray *buffers,
 IOStreamMode mode = kIOStreamModeOutput,
 IOItemCount queueLength = 0,
 OSDictionary *properties = 0); 
```

## Parameters

- `mode`: The initial mode of the stream, either output, input, or input/output.
- `queueLength`: The nuber of queue entries to reserve in the input and output queue. Zero means to make the queues big enough to accommodate all the buffers at once.
- `properties`: A dictionary of properties which will be set on the stream.
- `buffers`: An array of IOStreamBuffer objects which will be the buffers for this stream.
