Clearing up queues in C++

[Rajesh Khan]

I wanted to know what my options are when I need to clear up queues.
My first preference would be to clear them up programatically. I tried
setting a queue to auto-delete however that does not seem to work.I have a
sender and a receiver. The receiver creates a queue and sets the auto
delete parameter. However even after the receiver disconnects there still
is content in the queue. Is there any way of forcefully emptying a queue
using a command prompt ?
