|
// 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>The <STRONG>intrusive_ref_counter</STRONG> class template implements a reference counter for a derived
|
|
||||||
user's class that is intended to be used with <STRONG><a href="intrusive_ptr.html">intrusive_ptr</a></STRONG>.
|
|
||||||
The base class has associated <STRONG>intrusive_ptr_add_ref</STRONG> and <STRONG>intrusive_ptr_release</STRONG> functions
|
|
||||||
which modify the reference counter as needed and destroy the user's object when the counter drops to zero.</p>
|
|
||||||
<p>The class template is parameterized on <STRONG>DerivedT</STRONG> and <STRONG>CounterPolicyT</STRONG> parameters.
|
|
||||||
The first parameter is the user's class that derives from <STRONG>intrusive_ref_counter</STRONG>. This type
|
|
||||||
is needed in order to destroy the object correctly when there are no references to it left.</p>
|
|
||||||
<p>The second parameter is a policy that defines the nature of the reference counter.
|
|
||||||
Boost.SmartPtr provides two such policies: <STRONG>thread_unsafe_counter</STRONG> and <STRONG>thread_safe_counter</STRONG>. The former
|
|
||||||
instructs the <STRONG>intrusive_ref_counter</STRONG> base class to use a counter only suitable for a single-threaded use.
|
|
||||||
Pointers to a single object that uses this kind of reference counter must not be used in different threads. The latter policy
|
|
||||||
makes the reference counter thread-safe, unless the target platform doesn't support threading. Since in modern systems support for
|
|
||||||
threading is common, the default counter policy is <STRONG>thread_safe_counter</STRONG>.</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 shared
|
|
||||||
objects only. There was a need to have efficient allocation of
|
|
||||||
shared arrays. One criticism of class template <code>shared_array</code>
|
|
||||||
was always the lack of a <a href="make_shared.html">make_shared</a>
|
|
||||||
utility which ensures only a single allocation.</p>
|
|
||||||
<p>The header files <boost/smart_ptr/make_shared_array.hpp> and
|
|
||||||
<boost/smart_ptr/allocate_shared_array.hpp> provide function
|
|
||||||
templates, overloads of <code>make_shared</code> and
|
|
||||||
<code>allocate_shared</code> for array types, 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><b>Effects:</b> Allocates memory for an object of type <code>U</code>

||||||
where <code>size</code> is determined from <code>args</code> as
