[comp.sys.mac.programmer] "Printer Driver is MultiFinder Compatible"

earleh@eleazar.dartmouth.edu (Earle R. Horton) (03/04/89)

     The ResEdit 1.2b3 File Menu "Get Info..." box has a check box titled
"Printer Driver is MultiFinder Compatible."  All current Apple printer
drivers have this box checked.  Uh, what exactly does a printer driver
have to do to be MultiFinder Compatible?

This resource map attribute tells MultiFinder to load the file's resources
into the system heap.  It's rather like an override to each individual
resource's resSysHeap attribute.  It also allows an OpenResFile of the file
to succeed even if it was already open, so that application B can open it
even if application A has opened it and not yet closed it.
