Sorry if my message wasn't clear. I fully understand that, and wasn't
implying that FPC (FreeBSD) was wrong here. After my previous FreeBSD
messages and feedback, I knew where to look for the info, and the man
pages clearly said it is an opaque type.

As far as I know (I could be wrong though) Linux can't name threads. And
again, the code I'm working on in tiOPF is cross platform and cross
As I said, the Thread ID info is only used for debugging and not
something critical. There must just be some value differentiating
between various threads, when they output to the logger.
