/**

Declares a class as being non-sharable.

If a class is non-sharable, then a class implemented in another DLL cannot

derive (inherit) from that class.

Declaring a class as non-sharable prevents the compiler from exporting compiler

implementation-specific symbols, i.e. run-time type-information and virtual

tables. This prevents classes in other DLLs from being able to derive from it.

Note :

- if a class is marked as non-sharable, then Symbian OS requires all

classes that are derived from that class, and which are also implemented in the same DLL, 

to be declared as non-sharable.

- by default, a class is sharable.

The following code fragment shows how a non-sharable class is declared.

@code

NONSHARABLE_CLASS(CMyClass) : public CBase

	{

	public :

	...

	private :

	...

	}

@endcode

@param x  The name of the class to be declared as non-sharable.
