_com_ptr_t Relational Operators

Microsoft Specific

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

Syntax

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

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

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

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

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

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

bool operator==( int null );

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

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

template<typename _InterfaceType>
bool operator!=( _InterfaceType* p );

bool operator!=( int null );

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

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

template<typename _InterfaceType>
bool operator<( _InterfaceType* p );

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

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

template<typename _InterfaceType>
bool operator>( _InterfaceType* p );

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

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

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

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

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

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

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.
