Clearing up queues in C++
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 ?

Can you give more detail on the exact steps you took here? The
auto-delete setting should certainly work. Note that if the queue is
also exclusive then it will be auto-deleted when the session that
created it ends (not just on cancelling the receiver. Note also that
trying to set the auto-delete property on a queue already created won't
work.
If you can provide some steps to reproduce the non-functioning of
auto-delete, I can investigate some more.

Attached is a simple example program. However I would advise
investigating the autodelete issue a little more as I'm fairly confident
it will do as expected if used in the right manner.

While attempting to try this on the actual platform. I do not see the name
of the queue i want to empty using
qpid: list queue
Any idea on why it might be missing?

Thanks that seems to do the trick. Any idea how I could do it
programatically . The Programming in APACHE QPID does not have any
information regarding purge in C++ . Any suggestions ?

OK, how do you do it? Using qpid-tool you can:
1. connect to host
qpid-tool localhost:5672
qpid:
2. wait while qpid-tool loads everything
then list queues:
qpid: list queue
Object Summary:
ID Created Destroyed Index
================================================================================
128 21:24:47 - org.apache.qpid.broker:queue:topic-fjeld.1940.1
124 21:24:47 - org.apache.qpid.broker:queue:qmfc-v2-fjeld.1940.1
125 21:24:47 - org.apache.qpid.broker:queue:qmfc-v2-hb-fjeld.1940.1
126 21:24:47 - org.apache.qpid.broker:queue:qmfc-v2-ui-fjeld.1940.1
127 21:24:47 - org.apache.qpid.broker:queue:reply-fjeld.1940.1
3. Issue a purge command to one of the queues. Give it a request=0 and an empty filter={}
qpid: call 128 purge 0 {}
qpid: OK (0) - {}
You can get the management method list for any object class by using the 'schema' command:
qpid: schema queue

Queues have a purge management method that you can call from a command line utility or from within your code.
Method: purge
Argument Type Direction Unit Description
======================================================================================================
request uint32 I 0 for all messages or n>0 for n messages
filter field-table I if specified, purge only those messages matching this filter
