Getting Sides attribute

[Dan Masterson]

I have a server in which all jobs are held until my program releases them. I wish to find out if the job has been sent with duplexing options and to be able to force a job to duplex or not. Using ippFirstAttribute and ippNextAttribute I print out all attributes but even with jobs sent to be duplexed I do not see the sides attribute. Is there another way to ascertain if a job is to be duplexed or not?
