Detailed Description

An object of type thread::id provides a unique identifier for each thread of execution and a single distinct value for all thread objects that do not represent a thread of execution (33.3.2). Each thread of execution has an associated thread::id object that is not equal to the thread::id object of any other thread of execution and that is not equal to the thread::id object of any thread object that does not represent threads of execution.

thread::id shall be a trivially copyable class (Clause 12). The library may reuse the value of a thread::id of a terminated thread that can no longer be joined.
