Hi, I''m now implementing something similar to PGPS and I need some help. How to determine if a queue is backlog??? I''ve carried out some test using PRIO queue. It seems that the prio_dequeue is called right after prio_enqueue and therefore the q.qlen (queue length) is always zero!!!!! That''s mean there are no backlog queue at all. Please help!! Thanks in advance, William __________________________________________________ Do you Yahoo!? Yahoo!
