A detached pthread causes memory leaks

阅读更多关于 A detached pthread causes memory leaks

问题 There is a known memory leak, when terminating a process with running undetached pthreads. However, detaching the thread doesn't seem to be a solution. Consider the following minimal example: #include <pthread.h> #include <stdio.h> static void* thread(void* _) { for(;;); return NULL; } int main(void) { pthread_attr_t attr; pthread_attr_init(&attr); pthread_attr_setdetachstate(&attr, PTHREAD_CREATE_DETACHED); pthread_t tid; pthread_create(&tid, &attr, thread, NULL); pthread_attr_destroy(&attr)

Order of running threads in pthreads

阅读更多关于 Order of running threads in pthreads

In the following program, what are the possibilities for the ordering of threads? Assuming "function" will print thread id which is unique (since here we have only one process). I always get the order th1,th2! #include <stdlib.h> #include <stdio.h> #include <pthread.h> int main() { pthread_t th1; pthread_t th2; pthread_create(&th1, NULL, function, NULL); pthread_create(&th2, NULL, function, NULL); pthread_join(th1, NULL); pthread_join(th2, NULL); } return 0; } The only ordering guarantees here are that pthread_join(th1, NULL); will not return until thread 1 has exited and pthread_join(th2,

Java Multithreading concept and join() method

I'm confused in join() method used in Threads in Java. In the following code: // Using join() to wait for threads to finish. class NewThread implements Runnable { String name; // name of thread Thread t; NewThread(String threadname) { name = threadname; t = new Thread(this, name); System.out.println("New thread: " + t); t.start(); // Start the thread } // This is the entry point for thread. public void run() { try { for (int i = 5; i > 0; i--) { System.out.println(name + ": " + i); Thread.sleep(1000); } } catch (InterruptedException e) { System.out.println(name + " interrupted."); } System.out
