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

The class thread::id is a lightweight trivially copyable class used as a unique identifier of std::thread. Objects 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.

Member functions

(constructor)	constructs an id that does not represent a thread (public member function)

Non-member functions

operator== operator!= operator< operator<= operator> operator>=	compares two thread::id objects (function)
operator<<	serializes a thread::id object (function template)

Helper classes

std::hash<std::thread::id>	specializes std::hash (class template specialization)

get_id	returns the id of the thread (public member function)
