1.62 +Declares a class as being non-sharable.
1.63 +
1.64 +If a class is non-sharable, then a class implemented in another DLL cannot
1.65 +derive (inherit) from that class.
1.66 +
1.67 +Declaring a class as non-sharable prevents the compiler from exporting compiler
1.68 +implementation-specific symbols, i.e. run-time type-information and virtual
1.69 +tables. This prevents classes in other DLLs from being able to derive from it.
1.70 +
1.71 +Note :
1.72 +- if a class is marked as non-sharable, then Symbian OS requires all
1.73 +classes that are derived from that class, and which are also implemented in the same DLL,
1.74 +to be declared as non-sharable.
1.75 +- by default, a class is sharable.
1.76 +
1.77 +The following code fragment shows how a non-sharable class is declared.
1.78 +
1.79 +@code
1.80 +NONSHARABLE_CLASS(CMyClass) : public CBase

1.87 +@endcode
