pthread_detach memory leak

Detaching a thread using pthread_detach() informs the pthreads library that resources associated with this thread can be freed once the thread .... From the above code, I don't see any reason why valgrind, or any other memory leak checker, would comp, Using pthread_join() in the main thread (i.e. the thread that spawned the child) will ensure to fix the leak. For use cases where pthread_join() call is not required, calling pthread_detach with child pthread_t ensures the memory is released. From man fo, Returning from main is equivalent to an exit of the whole process, so this is in effect quite a rude way to terminate your detached thread. Your thread simply hasn't terminated when the main function ends, it only does so later when the exit mechanis, The pthread_join() or pthread_detach() function should eventually be called for every thread that is created with the detachstate attribute set to PTHREAD_CREATE_JOINABLE so that storage associated with the thread may be reclaimed. and from the man page , A thread's resources are not immediately released at termination, unless the thread was created with the detach state attribute set to PTHREAD_CREATE_DETACHED , or if pthread_detach is called for its pthread_t . An undetached thread will remain termi, glibc doesn't free thread stacks when threads exit; it caches them for reuse, and only prunes the cache when it gets huge. Thus it always "leaks" some memory., You should use either pthread_detach or pthread_join (but not both) on every pthread you create. pthread_join waits for the thread to finish; pthread_detach indicates that you don't intend to wait for it (hence the implementation is free to reclaim t, glibc's threads implementation intentionally leaks memory. It keeps the memory allocated to a thread context cached to reuse the next time a thread is created. I did some benchmarking versus an implementation without the caching, and it seems the cac, Therefore, pthread_join must be called once for each joinable thread created to avoid memory leaks. 才知道如果在新线程里面没有调用pthread_join 或pthread_detach会导致内存泄漏, 如果你创建的线程越多,你的内存利用率就会越高, 直到你再无法创建线程,最终只能结束进程。 解决方法有三个: 1. 线程里面 ...
