From natekohl.net

The C++ Extensions for Concurrency, ISO/IEC TS 19571:2016, defines the following new components for the C++ standard library:

Contents

[edit] Continuations and other extensions for std::future

Defined in header <experimental/future>
(concurrency TS)
A version of std::future enhanced with continuations and other features
(class template) [edit]
(concurrency TS)
A version of std::shared_future enhanced with continuations and other features
(class template) [edit]
(concurrency TS)
a modified version of std::promise that uses std::experimental::future
(class template)
(concurrency TS)
a modified version of std::packaged_task that uses std::experimental::future
(class template)
(concurrency TS)
produces a future that becomes ready when all given futures or shared_futures are ready
(function template) [edit]
(concurrency TS)
produces a future that becomes ready when at least one of the given futures or shared_futures is ready
(function template) [edit]
(concurrency TS)
produces a future that is ready immediately and holds the given value
(function template) [edit]
(concurrency TS)
produces a future that is ready immediately and holds the given exception
(function template) [edit]

[edit] Latches and barriers

Defined in header <experimental/latch>
(concurrency TS)
single-use thread barrier
(class) [edit]
Defined in header <experimental/barrier>
(concurrency TS)
reusable thread barrier
(class) [edit]
(concurrency TS)
reusable thread barrier with customizable behavior on completion
(class) [edit]

[edit] Atomic smart pointers

These class templates replace the shared_ptr atomic function overloads

Defined in header <experimental/atomic>
(concurrency TS)
atomic version of std::shared_ptr
(class template) [edit]
(concurrency TS)
atomic version of std::weak_ptr
(class template) [edit]


[edit] Feature test macros

a value of at least 201505 indicates that barrier type is supported
(macro constant)
Defined in header <experimental/atomic>
