Manager: Gestalt Manager

Carbon will fully support the Gestalt Manager. However, you should not use Gestalt functions to pass pointers to data among applications because each application will reside in its own protected memory space.

You should avoid using the NewGestalt function to add a selector code, which requires moving your selector function into the system heap. You should also avoid using the ReplaceGestalt function to replace an existing selector function, which also requires your replacement function to reside in the system heap. Note that you will not have access to the system heap in Mac OS X as you do in previous versions of the Mac OS.
