What is the function of pthread_create?

The pthread_create() function is used to create a new thread, with attributes specified by attr, within a process. If attr is NULL, the default attributes are used. If the attributes specified by attr are modified later, the thread’s attributes are not affected.

What is detached state in thread?

When a thread is created detached (PTHREAD_CREATE_DETACHED), its thread ID and other resources can be reused as soon as the thread terminates. So when you do not want a thread to be joined, create it as a detached thread.

Which type of thread is created by pthread_create API?

See pthread_self(3) for further information on the thread ID returned in *thread by pthread_create(). Unless real-time scheduling policies are being employed, after a call to pthread_create(), it is indeterminate which thread-the caller or the new thread-will next execute. A thread may either be joinable or detached.

What happens to a detached thread when main () exits?

7 Answers. The answer to the original question “what happens to a detached thread when main() exits” is: It continues running (because the standard doesn’t say it is stopped), and that’s well-defined, as long as it touches neither (automatic|thread_local) variables of other threads nor static objects.

What does .join do C++?

Join thread. The function returns when the thread execution has completed. This synchronizes the moment this function returns with the completion of all the operations in the thread: This blocks the execution of the thread that calls this function until the function called on construction returns (if it hasn’t yet).

How do you stop a detached thread?

There is no way to cleanly shutdown a detached thread. Doing so would require waiting for the cleanup to complete, and you can only do that if the thread is joinable. Consider, for example, if the thread holds a mutex that another thread needs to acquire in order to cleanly shut down.
