std::thread::joinable - cppreference.com

bool joinable() const noexcept;

(since C++11)

Checks if the std::thread object identifies an active thread of execution. Specifically, returns true if get_id() != std::thread::id(). So a default constructed thread is not joinable.

A thread that has finished executing code, but has not yet been joined is still considered an active thread of execution and is therefore joinable.

[edit] Parameters

(none)

[edit] Return value

true if the std::thread object identifies an active thread of execution, false otherwise.

[edit] Example

Output:

before starting, joinable: false
after starting, joinable: true
after joining, joinable: false
after detaching, joinable: false
