Thread

std::thread

Constructor

• thread() noexcept
  Creates a new std::thread object which does not represent a thread, so this instance should not call std::thread::join().

• thread(thread&& other) noexcept
  Move constructor. Constructs the std::thread object to represent the thread of execution that was represented by other. After this call other no longer represents a thread of execution.

  • other: another thread object to construct this thread object with.

• template< class F, class... Args > explict thread(F&& f, Args&&... args)
  Creates a new std::thread object and associates it with a thread of execution. The new thread of execution will start executing.

  • f: Callable object to execute in the new thread (a callable object can be seen as a function pointer, or an object of a class type that overloads operator().)
  • args: arguments to pass to the new function.

Note

• You can analogise thread constructor to pthread_create() in POSIX system, std::thread::join() to pthread_join().
• Threads begin execution immediately upon construction of the associated thread object.
• The arguments to the thread function are moved or copied by value. If a reference argument needs to be passed to the thread function, it has to be wrapped (e.g., with std::ref or std::cref).

   std::thread t1(f1,std::ref(n));

std::jthread

Note

std::jthread has the same general behavior as std::thread, except that jthread automatically rejoins on destruction, and can be cancelled/stopped in certain situations.
This class need C++20.
