    59 Declares a class as being non-sharable.
    60 
    61 If a class is non-sharable, then a class implemented in another DLL cannot
    62 derive (inherit) from that class.
    63 
    64 Declaring a class as non-sharable prevents the compiler from exporting compiler
    65 implementation-specific symbols, i.e. run-time type-information and virtual
    66 tables. This prevents classes in other DLLs from being able to derive from it.
    67 
    68 Note :
    69 - if a class is marked as non-sharable, then Symbian OS requires all
    70 classes that are derived from that class, and which are also implemented in the same DLL, 
    71 to be declared as non-sharable.
    72 - by default, a class is sharable.
    73 
    74 The following code fragment shows how a non-sharable class is declared.
    75 
    76 @code
    77 NONSHARABLE_CLASS(CMyClass) : public CBase
    78 {
    79 public :
    80 ...
    81 private :
    82 ...
    83 }
    84 @endcode
    85 
    86 @param x  The name of the class to be declared as non-sharable.
