ARM Type Attributes (Using the GNU Compiler Collection (GCC)) (original) (raw)

6.4.3.3 ARM Type Attributes ¶

On those ARM targets that support dllimport (such as Symbian OS), you can use the notshared attribute to indicate that the virtual table and other similar data for a class should not be exported from a DLL. For example:

class __declspec(notshared) C { public: __declspec(dllimport) C(); virtual void f(); }

__declspec(dllexport) C::C() {}

In this code, C::C is exported from the current DLL, but the virtual table for C is not exported. (You can use__attribute__ instead of __declspec if you prefer, but most Symbian OS code uses __declspec.)
