[thread.thread.class.general] (original) (raw)

The class thread provides a mechanism to create a new thread of execution, to join with a thread (i.e., wait for a thread to complete), and to perform other operations that manage and query the state of a thread.

A thread object uniquely represents a particular thread of execution.

That representation may be transferred to other thread objects in such a way that no two thread objects simultaneously represent the same thread of execution.

A thread of execution is detached when no thread object represents that thread.

Objects of class thread can be in a state that does not represent a thread of execution.

[Note 1:

A thread object does not represent a thread of execution after default construction, after being moved from, or after a successful call to detach orjoin.
