HSharableResource - Implements simple garbage collection for Mac OS Resources

HSharableResource is a Metrowerks powerPlant inherited class that implements simple garbage collection for Mac OS Resources. Using LSharable and TSharablePtr, the concept of reference counting makes this all possible. HSharableResource strives for Minimal reliance upon PowerPlant and could possibly be used in non-PowerPlant contexts. HSharablePicture is a variant upon PowerPlant`s LPicture class. It utilizes HSharableResource to manage the `PICT` resource so it can clean up after itself.The distribution contains the HSharableResource source, the HSharablePicture source, a CTYP file for HSharablePicture, and a small demonstration application. The files in the archive were created with CodeWarrior Professional 1.
