You can use the QUEUE DELETE request to delete all messages in the queue.
So for example:
$ STAF local HANDLE CREATE HANDLE NAME MyHandle
Response
--------
198
$ export STAF_STATIC_HANDLE=198
# Execute a process with notify onend, and do a queue get wait
$ STAF local PROCESS START SHELL COMMAND date RETURNSTDOUT NOTIFY ONEND
Response
--------
200
$ STAF local QUEUE GET WAIT 5000
Response
--------

Date-Time : 20081022-16:09:58
Machine : local://local
Handle Name: STAF_Process
Handle : 1
User : none://anonymous

Message : {

Enter the new date: (mm-dd-yy)
rc : 0
}
]
handle : 200
key :
rc : 1
}
}
# Now execute 3 processes with notify onend, and then do 4 queue get waits
$ STAF local PROCESS START SHELL COMMAND date RETURNSTDOUT NOTIFY ONEND
Response
--------
201
$ STAF local PROCESS START SHELL COMMAND date RETURNSTDOUT NOTIFY ONEND

[staf-users] Queue service question
Hi,
This is my scenario. I issue 10 process commands with the options
"notify onend" option on my local machine. Then I issue command
staf local get wait <timeoutvalue>
Now when 1st process finishes the queue command returns and that is
expected. Then I examine the result of the completed process. After that I
again issue the command
staf local get wait <anothertimeoutvalue>
Problem happens when multiple process finish. Now when I issue the
command
staf local get wait <anothertimeoutvalue>
This is probably because it has the notification from the second
completed process.
Is there a way I can clear the queue before issuing the command
again.
Thanks,
Arvind
