public static int streamPBIntoOutputStream(EventStream st,
                                           OutputStream os,
                                           Timestamp start,
                                           Timestamp end)
                                    throws IOException
```
    Push the events in st into the output stream os. This is highly simplistic and does not accommodate year transitions, pv transitions and such.
    
    Parameters:
    
    st - EventStream
    
    os - OutputStream
    
    start - The start time; could be null in which case we begin at the very beginning
    
    end - The end time; could be null in which case we end at the very end
    
    Returns:
    
    totalEvents
    
    Throws:
    
    IOException -
  - writeHeaderOnly
```
public static void writeHeaderOnly(OutputStream os,
                                   RemotableEventStreamDesc desc)
                            throws IOException
```
    Write a header only - this is sometimes used to communicate the latest copy of the meta-fields (EGU etc) from the engine to the client even if we have no data in the engine.
    
    Parameters:
    
    os - OutputStream
    
    desc - RemotableEventStreamDesc
