6.35.3 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
.)
