~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

(destructor)

if joinable() is true, calls request_stop() and then join(); in either case destructs the jthread object (public member function of std::jthread)
