# removeBuffer(IOStreamBuffer *)

Removes a buffer from the stream. Buffers cannot be removed while the stream is open, as this will change the buffer IDs of existing buffers.

## Declaration

```occ
virtual IOReturn removeBuffer(
 IOStreamBuffer *buffer); 
```

## Parameters

- `buffer`: A pointer to an IOStreamBuffer object in the stream.

## Return Value

Return Value Returns kIOReturnSuccess if the buffer was removed, or kIOReturnNotFound if the buffer was not in this stream.
