std::thread::id: std::thread::id


std::thread::id - std::thread::id


Defined in header <thread>
class thread::id; (since C++11)

The class thread::id is a lightweight, trivially copyable class that serves as a unique identifier of std::thread objects.
Instances of this class may also hold the special distinct value that does not represent any thread. Once a thread has finished, the value of std::thread::id may be reused by another thread.
This class is designed for use as key in associative containers, both ordered and unordered.
