template<typename _Interface, 
   typename _InterfacePtr> bool operator>=( 
   _Interface* i, 
   _com_ptr_t<_InterfacePtr>& p  
);

Parameters

• i
  A raw interface pointer.

• p
  A smart pointer.

Remarks

These function templates allow comparison with a smart pointer on the right side of the comparison operator. These are not member functions of _com_ptr_t.
