class thread; | (since C++11) |
The class thread represents a single thread of execution. Threads allow multiple pieces of code to run asynchronously and simultaneously.
std::thread objects may also be in the state that does not represent any thread (it gets into that state after default construction, a move from, detach, or join), and a thread of execution may be not associated with any thread objects (it gets into that state after detach). No two std::thread objects may represent the same thread of execution; std::thread is not CopyConstructible or CopyAssignable, although it is MoveConstructible and MoveAssignable.
Member types
| Member type | Definition |
|---|---|
native_handle_type | implementation-defined |
Member classes
| represents the id of a thread (public member class) |
Member functions
| constructs new thread object (public member function) | |
| (destructor)
| destructs the thread object, underlying thread must be joined or detached (public member function) |
| operator=
| moves the thread object (public member function) |
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 (public member function) | |
| [static] | returns the number of concurrent threads supported by the implementation (public static member function) |
Operations | |
| waits for a thread to finish its execution (public member function) | |
| permits the thread to execute independently from the thread handle (public member function) | |
| swaps two thread objects (public member function) | |
Non-member functions
| (C++11) | specializes the std::swap algorithm (function template) |
