create string from uid file????

System

I'm trying to get a list of users from a uid file. I created "approver.uid" and need to get at that list. What function does this?

The closest thing I found is on the concurrent_approver.wft that calls: get_names_from_file()
This builds a select box with the data in the uid. I just need the list to loop over and send an email.

please excuse my ignorance, I don't know perl or unix (oh boy!)
Thanks!
