[#make_local_shared]
# make_local_shared: Creating local_shared_ptr
:toc:
:toc-title:
:idprefix: make_local_shared_
## Description
The function templates `make_local_shared` and `allocate_local_shared` provide
convenient, safe and efficient ways to create `local_shared_ptr` objects. They
are analogous to `make_shared` and `allocate_shared` for `shared_ptr`.
## Synopsis
`make_local_shared` and `allocate_local_shared` are defined in
`<boost/smart_ptr/make_local_shared.hpp>`.
[subs=+quotes]
```
namespace boost {
`// only if T is not an array type`
template<class T, class... Args>
local_shared_ptr<T> make_local_shared(Args&&... args);
template<class T, class A, class... Args>
local_shared_ptr<T> allocate_local_shared(const A& a, Args&&... args);
`// only if T is an array type of the form U[]`
template<class T>
local_shared_ptr<T> make_local_shared(std::size_t n);
template<class T, class A>
local_shared_ptr<T> allocate_local_shared(const A& a, std::size_t n);
`// only if T is an array type of the form U[N]`
template<class T>
local_shared_ptr<T> make_local_shared();
template<class T, class A>
local_shared_ptr<T> allocate_local_shared(const A& a);
`// only if T is an array type of the form U[]`
template<class T>
local_shared_ptr<T> make_local_shared(std::size_t n,
const remove_extent_t<T>& v);
template<class T, class A>
local_shared_ptr<T> allocate_local_shared(const A& a, std::size_t n,
const remove_extent_t<T>& v);
`// only if T is an array type of the form U[N]`
template<class T>
local_shared_ptr<T> make_local_shared(const remove_extent_t<T>& v);
template<class T, class A>
local_shared_ptr<T> allocate_local_shared(const A& a,
const remove_extent_t<T>& v);
`// only if T is not an array type of the form U[]`
template<class T>
local_shared_ptr<T> make_local_shared_noinit();
template<class T, class A>
local_shared_ptr<T> allocate_local_shared_noinit(const A& a);
`// only if T is an array type of the form U[N]`
template<class T>
local_shared_ptr<T> make_local_shared_noinit(std::size_t n);
template<class T, class A>
local_shared_ptr<T> allocate_local_shared_noinit(const A& a,
std::size_t n);
}
```
## Description
The requirements and effects of these functions are the same as `make_shared`
and `allocate_shared`, except that a `local_shared_ptr` is returned.

they will share the single reference created in `make_shared_from_COM`. Weak pointers created from `pw` will be invalidated when the last
`shared_ptr` is destroyed, regardless of whether the COM object itself is still alive.
As link:../../libs/bind/mem_fn.html#Q3[explained] in the `mem_fn` documentation, you need to `#define BOOST_MEM_FN_ENABLE_STDCALL` first.
