QSettings usage for multiple processes

[Rohinee]

The default QSettings file format is the same as a Windows INI file, with a hierarchy of key=value fields within groups. If you have a way of giving a unique identifier to each of your parallel processes, then you can define top-level groups using those IDs as the group names. Within each of these top-level groups, you can then have the same subgroup / key-value hierarchy. When any process reads or writes parameters, it must first open the top-level group corresponding to its ID so it gets its own unique set.

I am not sure how you can define unique identifiers for the processes that will be persistent across different invocations. Perhaps there is something on stackoverflow with a solution to this problem.

Thank you! Will try this out.
