std::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
