+# allocate_unique: Creating unique_ptr
+:toc:
+:toc-title:
+:idprefix: allocate_unique_
+
+## Description
+
+The `allocate_unique` family of function templates provide convenient and safe
+ways to obtain a `std::unique_ptr` that manages a new object created using an
+allocator.
+
+## Rationale
+
+The {cpp}14 standard introduced `std::make_unique` which used operator `new` to
+create new objects. However, there is no convenient facility in the standard
+library to use an allocator for the creation of the objects managed by
+`std::unique_ptr`. Users writing allocator aware code have often requested an
+`allocate_unique` factory function. This function is to `std::unique_ptr` what
+`std::allocate_shared` is to `std::shared_ptr`.
+
+## Synopsis
+
+`allocate_unique` is defined in `<boost/smart_ptr/allocate_unique.hpp>`.
+
+[subs=+quotes]
+```
+namespace boost {
+  template<class T, class A>
+  class alloc_deleter;
+
+  template<class T, class A>
+  using alloc_noinit_deleter = alloc_deleter<T, noinit_adaptor<A>>;
+
+  `// T is not an array`
+  template<class T, class A, class... Args>
+    std::unique_ptr<T, alloc_deleter<T, A>>
+      allocate_unique(const A& a, Args&&... args);
+
+  `// T is not an array`
+  template<class T, class A>
+    std::unique_ptr<T, alloc_deleter<T, A>>
+      allocate_unique(const A& a, type_identity_t<T>&& v);
+
+  `// T is an array of unknown bounds`
+  template<class T, class A>
+    std::unique_ptr<T, alloc_deleter<T, A>>
+      allocate_unique(const A& a, std::size_t n);
+
+  `// T is an array of known bounds`
+  template<class T, class A>
+    std::unique_ptr<remove_extent_t<T>[], alloc_deleter<T, A>>
+      allocate_unique(const A& a);
+
+  `// T is an array of unknown bounds`
+  template<class T, class A>
+    std::unique_ptr<T, alloc_deleter<T, A>>
+      allocate_unique(const A& a, std::size_t n, const remove_extent_t<T>& v);
+
+  `// T is an array of known bounds`
+  template<class T, class A>
+    std::unique_ptr<remove_extent_t<T>[], alloc_deleter<T, A>>
+      allocate_unique(const A& a, const remove_extent_t<T>& v);
+
+  `// T is not an array`
+  template<class T, class A>
+    std::unique_ptr<T, alloc_noinit_deleter<T, A>>
+      allocate_unique_noinit(const A& a);
+
+  `// T is an array of unknown bounds`
+  template<class T, class A>
+    std::unique_ptr<T, alloc_noinit_deleter<T, A>>
+      allocate_unique_noinit(const A& a, std::size_t n);
+
+  `// T is an array of known bounds`
+  template<class T, class A>
+    std::unique_ptr<remove_extent_t<T>[], alloc_noinit_deleter<T, A>>
+      allocate_unique_noinit(const A& a);
+}
+```
+
+## Common Requirements
+
+The common requirements that apply to all `allocate_unique` and
+`allocate_unique_noinit` overloads, unless specified otherwise, are described
+below.
+
+Requires:: `A` shall be an _allocator_. The copy constructor and destructor
+of `A` shall not throw exceptions.
+
+Effects:: Allocates memory for an object of type `T` or `n` objects of `U`
+(if `T` is an array type of the form `U[]` and  `n` is determined by
+arguments, as specified by the concrete overload). The object is initialized
+from arguments as specified by the concrete overload. Uses a rebound copy of
+`a` (for an unspecified `value_type`) to allocate memory. If an exception is
+thrown, the functions have no effect.
+
+Returns:: A `std::unique_ptr` instance that stores and owns the address of the
+newly constructed object.
+
+Postconditions:: `r.get() != 0`, where `r` is the return value.
+
+Throws:: An exception thrown from `A::allocate`, or from the initialization of
+the object.
+
+Remarks::
+* When an object of an array type is specified to be initialized to a value of
+the same type `v`, this shall be interpreted to mean that each array element

+# enable_shared_from
+:toc:
+:toc-title:
+:idprefix: enable_shared_from_
+
+## Description
+
+`enable_shared_from` is used as a base class that allows a `shared_ptr` or a
+`weak_ptr` to be obtained given a raw pointer to the object, by using the
+functions `shared_from` and `weak_from`.
+
+`enable_shared_from` differs from `enable_shared_from_this<T>` by the fact
+that it's not a template, and is its recommended replacement for new code.
+
+## Example
+
+```
+#include <boost/smart_ptr/enable_shared_from.hpp>
+#include <boost/shared_ptr.hpp>
+#include <cassert>
+
+class Y: public boost::enable_shared_from
+{
+public:
+
+    boost::shared_ptr<Y> f()
+    {
+        return boost::shared_from( this );
+    }
+};
+
+int main()
+{
+    boost::shared_ptr<Y> p(new Y);
+    boost::shared_ptr<Y> q = p->f();
+    assert(p == q);
+    assert(!(p < q || q < p)); // p and q must share ownership
+}
+```
+
+## Synopsis
+
+`enable_shared_from` is defined in `<boost/smart_ptr/enable_shared_from.hpp>`.
+
+```
+namespace boost {
+
+  class enable_shared_from: public enable_shared_from_this<enable_shared_from>
+  {

+  template<class T> weak_ptr<T> weak_from( T * p ) noexcept;

+[none]
+* {blank}
++
+Returns:: `shared_ptr<T>( p\->enable_shared_from::shared_from_this(), p )`.

+      and returns a `weak_ptr` that is `expired()` but still shares ownership
+      with other `weak_ptr` instances (if any) that refer to the object.
