_com_ptr_t Relational Operators

Microsoft Specific

template<typename _InterfacePtr> bool operator==( _InterfacePtr p ) throw( _com_error );

template<> bool operator==( Interface* p ) throw( _com_error );

template<> bool operator==( _com_ptr_t& p ) throw( );

template<> bool operator==( int NULL ) throw( _com_error );

template<typename _InterfacePtr> bool operator!=( _InterfacePtr p ) throw( _com_error );

template<> bool operator!=( Interface* p ) throw( _com_error );

template<> bool operator!=( _com_ptr_t& p ) throw( _com_error );

template<> bool operator!=( int NULL ) throw( _com_error );

template<typename _InterfacePtr> bool operator<( _InterfacePtr p ) throw( _com_error );

template<typename _InterfacePtr> bool operator>( _InterfacePtr p ) throw( _com_error );

template<typename _InterfacePtr> bool operator<=( _InterfacePtr p ) throw( _com_error );

template<typename _InterfacePtr> bool operator>=( _InterfacePtr p ) throw( _com_error );

Remarks

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.
