Fork in CUPS filter

[Ralph Majer]

Hi

i've written a small CUPS Filter in C++ for some printjob statistics.
In this filter I'm forking away because for larger printjobs it takes a lot of time to process them. So the parent process finishes very fast and CUPS should go on with the filter chain.

But I've noticed that CUPS is also waiting until the child process of the filter is finished.
Is it not possible just to fork away??
I found nothing about it in the documentation.

I hope anybody can give me some advice?

Regards
