Hi,
I send already in one of my last answers to Anton's question on TThread
some very simple example macros, which show how threads can be created and
used.
Nevertheless, as we also said it several times, there will be a HOWTO,
provided by us, for the usage of the TThread-class. Additionally, we will
also provide a chapter of the ROOT users manual on threading.
So please be kind and search the digest for what we from GSI have already
mentioned to the roottalk and look at the ROOT Workshop. There will be
more documentation available.
Greetings,
Marc
