[cups.development] How to read all groups mentioned in PPD file?

[Mangesh Kute]

Hi,

How to read all groups mentioned in PPD file?
I am trying to create user interface showing all configurable options
in PPD file.
ppdOpenFIle reads PPD file in memory. But it only reads first group.
How to read subsequent groups in PPD file ?

Regards,
Mangesh
