williamr@4: Declares a class as being non-sharable.
williamr@4: 
williamr@4: If a class is non-sharable, then a class implemented in another DLL cannot
williamr@4: derive (inherit) from that class.
williamr@4: 
williamr@4: Declaring a class as non-sharable prevents the compiler from exporting compiler
williamr@4: implementation-specific symbols, i.e. run-time type-information and virtual
williamr@4: tables. This prevents classes in other DLLs from being able to derive from it.
williamr@4: 
williamr@4: Note :
williamr@4: - if a class is marked as non-sharable, then Symbian OS requires all
williamr@4: classes that are derived from that class, and which are also implemented in the same DLL, 
williamr@4: to be declared as non-sharable.
williamr@4: - by default, a class is sharable.
williamr@4: 
williamr@4: The following code fragment shows how a non-sharable class is declared.
