NAME
std::tr1::shared_ptr -
SYNOPSIS
Detailed Description
template<typename _Tp> class std::tr1::shared_ptr< _Tp >
A smart pointer with reference-counted copy semantics. The object pointed to is deleted when the last
shared_ptr pointing to it is destroyed or reset.

Constructor & Destructor Documentation
Construct an empty shared_ptr.
Postcondition:
use_count()==0 && get()==0
Definition at line 496 of file boost_shared_ptr.h.
shared_ptr (_Tp1 * __p) [inline, explicit]
Construct a shared_ptr that owns the pointer p.
Parameters:
p A pointer that is convertible to element_type*.
Postcondition:
use_count() == 1 && get() == p
Exceptions:
std::bad_alloc,in which case delete p is called.
Definition at line 506 of file boost_shared_ptr.h.
References __glibcxx_function_requires.
shared_ptr (_Tp1 * __p, _Deleter __d) [inline]
Construct a shared_ptr that owns the pointer p and the deleter d.
Parameters:
p A pointer.
d A deleter.
Postcondition:
use_count() == 1 && get() == p
Exceptions:
std::bad_alloc,in which case d(p) is called.

References __glibcxx_function_requires.
shared_ptr (const shared_ptr< _Tp1 > & __r) [inline]
If r is empty, constructs an empty shared_ptr; otherwise construct a shared_ptr that shares ownership with r.
Parameters:
r A shared_ptr.
Postcondition:
get() == r.get() && use_count() == r.use_count()
Exceptions:
std::bad_alloc,in which case

shared_ptr (const weak_ptr< _Tp1 > & __r) [inline, explicit]
Constructs a shared_ptr that shares ownership with r and stores a copy of the pointer stored in r.
Parameters:
r A weak_ptr.
Postcondition:
use_count() == r.use_count()
Exceptions:
bad_weak_ptr when r.expired(), in which case the constructor has no effect.
