# std::thread::~thread

From cppreference.com
< cpp‎ | thread‎ | thread

~thread(); |  | (since C++11)

Destroys the thread object.

If *this has an associated thread (joinable() == true), std::terminate () is called.

### Notes

A thread object does not have an associated thread (and is safe to destroy) after

- it was default-constructed.
- it was moved from.
- join() has been called.
- detach() has been called.

### Example

Run this code

    #include <thread>
    using namespace std::chrono_literals;

    int main()
    {
        auto bleah = std::thread{[]{ std::this_thread::sleep_for(13ms); }};

    }   // ~thread calls std::terminate()

Possible output:

    terminate called without an active exception
