void join();		(since C++11)

Blocks the current thread until the thread identified by *this finishes its execution.

The completion of the thread identified by *this synchronizes with the corresponding successful return from join().

Parameters

(none)

Return value

(none)

Postconditions

joinable is false

Exceptions

std::system_error if an error occurs.

Error Conditions

• resource_deadlock_would_occur if this->get_id() == std::this_thread::get_id() (deadlock detected)
• no_such_process if the thread is not valid
• invalid_argument if joinable is false
