classthread;(since C++11)The class thread represents
. Threads allow multiple functions to execute concurrently.
Threads begin execution immediately upon construction of the associated thread object (pending any OS scheduling delays), starting at the top-level function provided as a
. The return value of the top-level function is ignored and if it terminates by throwing an exception,
is called. The top-level function may communicate its return value or an exception to the caller via
or by modifying shared variables (which may require synchronization, see
and
).
std::thread objects may also be in the state that does not represent any thread (after default construction, move from,
, or
), and a thread of execution may not be associated with any thread objects (after
).
No two std::thread objects may represent the same thread of execution; std::thread is not

Observers
checks whether the thread is joinable, i.e. potentially running in parallel context
(public member function)
returns the id of the thread
(public member function)
returns the underlying implementation-defined thread handle

[static]
returns the number of concurrent threads supported by the implementation
(public static member function)
Operations
