The pthread_cond_destroy() function shall destroy the given condition variable specified by cond; the object becomes, in effect,uninitialized. An implementation may cause pthread_cond_destroy() to set the object referenced by cond to an invalid value. A destroyed conditionvariable object can be reinitialized … See more #include int pthread_cond_destroy(pthread_cond_t *cond); int pthread_cond_init(pthread_cond_t *restrict cond, … See more A condition variable can be destroyed immediately after all the threads that are blocked on it are awakened. For example, consider the following … See more If successful, the pthread_cond_destroy() and pthread_cond_init() functions shall return zero; otherwise, an error number shall be returned … See more The pthread_cond_destroy() function may fail if: EBUSY 1.

Web当调用 pthread_join() 时，当前线程会处于阻塞状态，直到被调用的线程结束后，当前线程才会重新开始执行。pthread_join() 函数返回后，被调用线程才算真正意义上的结束，它的内存空间也会被释放（如果被调用线程是非分离的）。这里有三点需要注意： WebAug 12, 2013 · Linux--17： linux 多线程之函数pthread_cond_init（）和函数 pthread_cond_wait（）. 最近找到一篇很好的文章将linux多线程函数pthread_cond_wait，是我茅塞顿开，豁然开朗，决定转载过来，以便经常复习记忆。. 条件变量的结构为pthread_cond_t，函数pthread_cond_init（）被用来初始化 ... tier list bloodline shindo life atualizado
