Add a function to add the number of licenses you want to be borrowed from the licese server.
when you have 20 licenses you do not want them all to be borrowed but just a small number
You can set this number in applications like Autodesk who are also using Flexlm as license manager, this can be done in the options file:
BORROW_LOWWATER
BORROW_LOWWATER feature[:keyword=value] n
Sets the number of licenses for a BORROW feature that cannot be borrowed.
