[comp.sys.mac.programmer] How to check if MultiFinder is running in System 6.0?

thomas@uvabick.UUCP (Thomas Fruin) (06/14/88)

A friend of mine ran into problems with his software when System 6.0 
came out.  He needs to check if he is running under Uni- or MultiFinder,
and needs to sublaunch another application if the environment is
MultiFinder.

Up to now, he did this by checking if the WaitNextEvent trap was
implemented, but it appears the new Finder 6.1 also supports WNE.
I do recall someone mentioning somewhere that this would eventually
happen, so what I would like to know is ...

What is the current 'officially sanctioned' way of determining if one
is running Uni- or MultiFinder?
