# std::experimental::packaged_task (concurrency TS)

From cppreference.com
< cpp‎ | experimental‎ | concurrency

This page is about the modified version of std::packaged_task provided by the concurrency TS supporting the `std::future` improvements made by that TS. For the version of `packaged_task` with type-erased allocator support provided by the Library Fundamentals TSes, see `std::experimental::fundamentals_v2::packaged_task`.

Defined in header `<experimental/future>` |  |

template< class R, class ...Args > class packaged_task<R(Args...)>; | (2) | (concurrency TS)

`std::experimental::concurrency_v1::packaged_task` is a modified version of std::packaged_task provided by the concurrency TS that works with std::experimental::future.

The only change from std::packaged_task is that the `get_future()` member function returns a std::experimental::future<R>.
