Yes, and that's wrong. "return *grp" returns and instance of a Group, but the function is declared to return a pointer to a Group, so it won't compile. (The example is meant to demonstrate a common coding mistake, but it should at least compile. :-) The example should be changed to read "return grp.get()". This is the "correct" way to demonstrate returning a dangling pointer (something you should never do). -Paul _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
