🔗
void swap(jthread& x) noexcept;
1
#
Effects: Exchanges the values of *this and x.
🔗
[[nodiscard]] bool joinable() const noexcept;
2
#
Returns: get_id() != id().
🔗
void join();
3
#
Effects: Blocks until the thread represented by *this has completed.
4
#
Synchronization: The completion of the thread represented by *this synchronizes with ([intro.multithread]) the corresponding successful join() return.
[Note 1: 
Operations on *this are not synchronized.
— end note]
5
#
Postconditions: The thread represented by *this has completed.
get_id() == id().
6
#
Throws: system_error when an exception is required ([thread.req.exception]).
7
#
Error conditions:
  • (7.1)
    resource_deadlock_would_occur — if deadlock is detected or get_id() == this_thread​::​​get_id().
  • (7.2)
    no_such_process — if the thread is not valid.
  • (7.3)
    invalid_argument — if the thread is not joinable.
🔗
void detach();
8
#
Effects: The thread represented by *this continues execution without the calling thread blocking.
When detach() returns, *this no longer represents the possibly continuing thread of execution.
When the thread previously represented by *this ends execution, the implementation releases any owned resources.
9
#
Postconditions: get_id() == id().
10
#
Throws: system_error when an exception is required ([thread.req.exception]).
11
#
Error conditions:
  • (11.1)
    no_such_process — if the thread is not valid.
  • (11.2)
    invalid_argument — if the thread is not joinable.
🔗
id get_id() const noexcept;
12
#
Returns: A default constructed id object if *this does not represent a thread, otherwise this_thread​::​get_id() for the thread of execution represented by *this.
