The queue length.
Description
Normally queue-length simply returns a count
that is maintained with the queue. Although highly unlikely, this
count could become inaccurate if queue-element insertion or
deletion operations are aborted in process. If recount-p is
true, the elements are actually counted and then the count maintained
with the queue is updated and returned.
Examples
Return the number of KSAs in the queue pending-ksas:
> (queue-length pending-ksas) 896 >Count and then return the actual number of KSAs in the queue
pending-ksas:
> (queue-length pending-ksas 't) 896 >
