1.49 +Declares a class as being non-sharable.
1.50 +
1.51 +If a class is non-sharable, then a class implemented in another DLL cannot
1.52 +derive (inherit) from that class.
1.53 +
1.54 +Declaring a class as non-sharable prevents the compiler from exporting compiler
1.55 +implementation-specific symbols, i.e. run-time type-information and virtual
1.56 +tables. This prevents classes in other DLLs from being able to derive from it.
1.57 +
1.58 +Note :
1.59 +- if a class is marked as non-sharable, then Symbian OS requires all
1.60 +classes that are derived from that class, and which are also implemented in the same DLL,
1.61 +to be declared as non-sharable.
1.62 +- by default, a class is sharable.
1.63 +
1.64 +The following code fragment shows how a non-sharable class is declared.
1.65 +@code
1.66 +NONSHARABLE_CLASS(CMyClass) : public CBase
1.67 + {

1.70 + private :
1.71 + ...
1.72 + }
1.73 +@endcode
1.74 +
1.75 +@param x The name of the class to be declared as non-sharable.
