Classes
class	ACE_Auto_Basic_Ptr< X >
	Implements the draft C++ standard auto_ptr abstraction. This class allows one to work on non-object (basic) types. More...
class	auto_ptr< X >
	Implements the draft C++ standard auto_ptr abstraction. More...
class	ACE_Auto_Ptr< X >
	Implements the draft C++ standard auto_ptr abstraction. This version can be used instead of auto_ptr<T>, and obviates the need for the ACE_AUTO_PTR_RESET macro on platforms like VC6 where the auto_ptr<T> is broken. More...
class	ACE_Auto_Basic_Array_Ptr< X >
	Implements an extension to the draft C++ standard auto_ptr abstraction. This class allows one to work on non-object (basic) types that must be treated as an array, e.g., deallocated via "delete [] foo". More...
class	ACE_Auto_Array_Ptr< X >
	Implements an extension to the draft C++ standard auto_ptr abstraction. More...
Functions
template<typename AUTO_PTR_TYPE , typename PTR_TYPE >
void	ACE_auto_ptr_reset (AUTO_PTR_TYPE &ap, PTR_TYPE *p)
	Reset given auto_ptr element to new element.

Function Documentation

template<typename AUTO_PTR_TYPE , typename PTR_TYPE >

void ACE_auto_ptr_reset	(	AUTO_PTR_TYPE &	ap,
		PTR_TYPE *	p
	)			[inline]

Reset given auto_ptr element to new element.

Some platforms have an older version of auto_ptr support, which lacks reset, and cannot be disabled easily. Portability to these platforms requires use of this function template. This function template also works for the ACE_Auto_{Basic_}Array_Ptr class template, as well.
