Detailed Description

template<class I>
struct comstl::IID_traits< I >

Interface identifier traits.

This traits class takes an interface type and provides a specialisation that has a statid iid() method which returns the interface identifier (IID) for that type.

To use, simply have the expression IID_traits<I>::iid() where I is your interface type.

On compilers that support the __uuidof pseudo-operator this is used, otherwise you must specify specialisations - using the COMSTL_IID_TRAITS_DEFINE macro - for your interfaces, as in

COMSTL_IID_TRAITS_DEFINE(IMyInterface)

All the interfaces currently defined in unknown.idl and objidl.idl are so defined in the file comstl_interface_traits_std.h, which is included in for non-__uuidof compilations.

Parameters:

I

The interface
