new function in queue.h

[Vicent Pla <vpla@seas.upenn.edu>]

Hi,

I want to add a new function member to the class 'PacketQueue' such that
the queue length in bytes could be queried. However, whatever the
function is, even if it is never called, I got :

Bus Error (core dumped)

Can somebody help me ?

Yuri: I found a message in the archives

you managed ? How ?

Thanks
