williamr@2: Declares a class as being non-sharable.
williamr@2: 
williamr@2: If a class is non-sharable, then a class implemented in another DLL cannot
williamr@2: derive (inherit) from that class.
williamr@2: 
williamr@2: Declaring a class as non-sharable prevents the compiler from exporting compiler
williamr@2: implementation-specific symbols, i.e. run-time type-information and virtual
williamr@2: tables. This prevents classes in other DLLs from being able to derive from it.
williamr@2: 
williamr@2: Note :
williamr@2: - if a class is marked as non-sharable, then Symbian OS requires all
williamr@2: classes that are derived from that class, and which are also implemented in the same DLL, 
williamr@2: to be declared as non-sharable.
williamr@2: - by default, a class is sharable.
williamr@2: 
williamr@2: The following code fragment shows how a non-sharable class is declared.
williamr@2: @code
williamr@2: NONSHARABLE_CLASS(CMyClass) : public CBase
williamr@2: 	{
