_com_ptr_t Relational Operators

Microsoft Specific

Compare the smart pointer object to another smart pointer, raw interface pointer, or NULL.

template<typename _OtherIID> 
bool operator==( 
   const _com_ptr_t<_OtherIID>& p 
); 

template<typename _OtherIID>

); 

template<typename _InterfaceType> 
bool operator==( 
   _InterfaceType* p

Compares a smart pointer object to another smart pointer, raw interface pointer, or NULL. Except for the NULL pointer tests, these operators first query both pointers for IUnknown, and compare the results.
