Syntax

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

template<typename _Interface> bool operator!=(

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