Can a thread join itself?





Summary of the Article

What happens if a thread joins itself

The call returns immediately indicating an error. The call returns immediately indicating a successful completion. A thread cannot join itself – a deadlock would occur and it is detected by the library.

What is a joined thread

Edit online. Joining a thread means waiting for it to terminate, which can be seen as a specific usage of condition variables. Waiting for a thread. Using the pthread_join subroutine alows a thread to wait for another thread to terminate.

What is true about join in threads

Join is a synchronization method that blocks the calling thread (that is, the thread that calls the method) until the thread whose Join method is called has completed. Use this method to ensure that a thread has been terminated. The caller will block indefinitely if the thread does not terminate.

Do threads have to be joined

Threads can be either joinable or detached. Detached threads should not be joined. On the other hand, if you didn’t join the joinable thread, you app would leak some memory and some thread structures. c++11 std::thread would call std::terminate, if it wasn’t marked detached and thread object went out of scope without .

Can a thread interrupt itself

The interrupt() method is a method of the Thread class, and it is used by one thread to signal another thread: it is possible (although it doesn’t really make sense) for a thread to interrupt itself. The target thread knows it has been interrupted if it is executing a method that will throw an InterruptedException.

Can a single thread deadlock itself

It is impossible to have circular-wait when there is only one single-threaded process. There is no second process to form a circle with the first one. One process cannot hold a resource, yet be waiting for another resource that it is holding. So it is not possible to have a deadlock involving only one process.

Can we join two threads

A thread cannot join itself because a deadlock would occur and it is detected by the library. However, two threads may try to join each other. They will deadlock, but this situation is not detected by the library. The pthread_join subroutine also allows a thread to return information to another thread.

Can you join a thread twice

No. After starting a thread, it can never be started again. If you does so, an IllegalThreadStateException is thrown. In such case, thread will run once but for second time, it will throw exception.

Which of the following is not true about threads

swithcing between threads of same process takes less time as next-to-run thread shares same address space. ANSWER: From the above given options, the statement which is not correct about the threads of any process is option 2) Inter-thread communication is faster as the threads of one process is share address space.

Does a thread get its own stack

Distinguishing between these kinds of memory matters because each thread will have its own stack. However, all the threads in a process will share the heap. Some people call threads lightweight processes because they have their own stack but can access shared data.

Can you join a detached thread

Only threads that are created as joinable can be joined. If a thre

Can you join a detached thread

Only threads that are created as joinable can be joined. If a thread is created as detached, it can never be joined.

Can a Java thread interrupt itself

interrupt() does not throw any exceptions by itself. It does two things: First it simply sets an internal interrupted-flag and then it checks if the thread that it was called on is currently blocking on an activity like wait() , sleep() , or join() .

How do you make a thread stop itself

Whenever we want to stop a thread from running state by calling stop() method of Thread class in Java. This method stops the execution of a running thread and removes it from the waiting threads pool and garbage collected. A thread will also move to the dead state automatically when it reaches the end of its method.

Can a thread close itself

A thread automatically terminates when it returns from its entry-point routine. A thread can also explicitly terminate itself or terminate any other thread in the process, using a mechanism called cancelation.

How do you connect threads together

And I thread my end through the loop. And I pull the two ends tight. From here I'm almost there I'm not quite there yet but you actually want to hear feel if it's going to pop.

Do threads have their own stack

Does each thread get its own stack

Can a thread cancel itself

A thread automatically terminates when it returns from its entry-point routine. A thread can also explicitly terminate itself or terminate any other thread in the process, using a mechanism called cancelation.

Which of the following statements are true about threads

True, Threads are dependent on other processes. Threads share with other threads their code section, data section, and OS resources, and a thread has its own program counter (PC), register set, and stack space.

Which statement is incorrect about thread

Answer» D. A thread can exist only in two states, running and blocked.

Can one thread create another thread

Yes. The typical problem, however, is that the work/threads are not constrained.

Do threads have their own kernel stack

Each process has a kernel stack (or more generally, each thread has its own stack)

What happens if you don’t detach thread

Whenever a thread terminates without detaching, the thread's stack is deallocated, but some other resources, including the thread ID and exit status, are left until it is destroyed by either thrd_join() or thrd_detach() .

Can threads interact with each other

Inter-thread communications allow threads to talk to or wait on each other. Again, because all the threads in a program share the same memory space, it is possible for two threads to access the same variables and methods in object.

Will thread automatically be killed

A thread automatically terminates when it returns from its entry-point routine. A thread can also explicitly terminate itself or terminate any other thread in the process, using a mechanism called cancelation.
