// typedef <implementation-defined> boost::detail::atomic_count;
//
// atomic_count a(n);
//
// (n is convertible to long)
//
// Effects: Constructs an atomic_count with an initial value of n
//
// a;
//
// Returns: (long) the current value of a
//
// ++a;
//
// Effects: Atomically increments the value of a
// Returns: nothing
//
// --a;
//
// Effects: Atomically decrements the value of a
// Returns: (long) zero if the new value of a is zero,
// unspecified non-zero value otherwise (usually the new value)
//
// Important note: when --a returns zero, it must act as a
// read memory barrier (RMB); i.e. the calling thread must
// have a synchronized view of the memory
//
// On Intel IA-32 (x86) memory is always synchronized, so this
// is not a problem.
//
// On many architectures the atomic instructions already act as
// a memory barrier.
//
// This property is necessary for proper reference counting, since
// a thread can update the contents of a shared object, then
// release its reference, and another thread may immediately
// release the last reference causing object destruction.
//
// The destructor needs to have a synchronized view of the
// object to perform proper cleanup.
//
// Original example by Alexander Terekhov:
//
// Given:
//
// - a mutable shared object OBJ;
// - two threads THREAD1 and THREAD2 each holding
// a private smart_ptr object pointing to that OBJ.
//
// t1: THREAD1 updates OBJ (thread-safe via some synchronization)
// and a few cycles later (after "unlock") destroys smart_ptr;
//
// t2: THREAD2 destroys smart_ptr WITHOUT doing any synchronization
// with respect to shared mutable object OBJ; OBJ destructors
// are called driven by smart_ptr interface...

// typedef <implementation-defined> boost::detail::atomic_count;
//
// atomic_count a(n);
//
// (n is convertible to long)
//
// Effects: Constructs an atomic_count with an initial value of n
//
// a;
//
// Returns: (long) the current value of a
//
// ++a;
//
// Effects: Atomically increments the value of a
// Returns: (long) the new value of a
//
// --a;
//
// Effects: Atomically decrements the value of a
// Returns: (long) the new value of a
//
// Important note: when --a returns zero, it must act as a
// read memory barrier (RMB); i.e. the calling thread must
// have a synchronized view of the memory
//
// On Intel IA-32 (x86) memory is always synchronized, so this
// is not a problem.
//
// On many architectures the atomic instructions already act as
// a memory barrier.
//
// This property is necessary for proper reference counting, since
// a thread can update the contents of a shared object, then
// release its reference, and another thread may immediately
// release the last reference causing object destruction.
//
// The destructor needs to have a synchronized view of the
// object to perform proper cleanup.
//
// Original example by Alexander Terekhov:
//
// Given:
//
// - a mutable shared object OBJ;
// - two threads THREAD1 and THREAD2 each holding
// a private smart_ptr object pointing to that OBJ.
//
// t1: THREAD1 updates OBJ (thread-safe via some synchronization)
// and a few cycles later (after "unlock") destroys smart_ptr;
//
// t2: THREAD2 destroys smart_ptr WITHOUT doing any synchronization
// with respect to shared mutable object OBJ; OBJ destructors
// are called driven by smart_ptr interface...

<h2><a name="Introduction">Introduction</a></h2>
<p>Consistent use of <a href="shared_ptr.htm"><code>shared_ptr</code></a>
can eliminate the need to use an explicit <code>delete</code>,
but alone it provides no support in avoiding explicit <code>new</code>.
There have been repeated requests from users for a factory function that creates
an object of a given type and returns a <code>shared_ptr</code> to it.
Besides convenience and style, such a function is also exception safe and
considerably faster because it can use a single allocation for both the object
and its corresponding control block, eliminating a significant portion of
<code>shared_ptr</code>'s construction overhead.
This eliminates one of the major efficiency complaints about <code>shared_ptr</code>.
</p>
<p>The header file &lt;boost/make_shared.hpp&gt; provides a family of overloaded function templates,
<code>make_shared</code> and <code>allocate_shared</code>, to address this need.
<code>make_shared</code> uses the global operator <code>new</code> to allocate memory,
whereas <code>allocate_shared</code> uses an user-supplied allocator, allowing finer control.</p>
<p>
The rationale for choosing the name <code>make_shared</code> is that the expression
<code>make_shared&lt;Widget&gt;()</code> can be read aloud and conveys the intended meaning.</p>

<h2><a name="Introduction">Introduction</a></h2>
<p>Originally the Boost function templates <code>make_shared</code> and
<code>allocate_shared</code> were for efficient allocation of single
objects only. There was a need to have efficient, single, allocation of
arrays. One criticism of <a href="shared_array.htm">shared_array</a> was
always the lack of a <a href="make_shared.html">make_shared</a> utility
which ensures only a single allocation for an array.</p>
<p>The header files &lt;boost/smart_ptr/make_shared_array.hpp&gt; and
&lt;boost/smart_ptr/allocate_shared_array.hpp&gt; provide new function
templates, <code>make_shared</code> and <code>allocate_shared</code>,
to address this need. <code>make_shared</code> uses the global
operator <code>new</code> to allocate memory, whereas
<code>allocate_shared</code> uses an user-supplied allocator,
allowing finer control.</p>

The implementation questions revolved around the reference count which must be

those variants have themselves two major variants:
<ul>
<li>
Direct detached: the shared_ptr contains a pointer to the object, and a pointer
Direct detached: the shared_ptr contains a pointer to the object, and a pointer
to the count.
<li>
Indirect detached: the shared_ptr contains a pointer to a helper object, which
Indirect detached: the shared_ptr contains a pointer to a helper object, which
in turn contains a pointer to the object and the count.
<li>
Embedded attached: the count is a member of the object pointed to.
<li>
Placement attached: the count is attached via operator new manipulations.</li>
</ul>
<p>Each implementation technique has advantages and disadvantages. We went so far
