LINUX 多线程加锁

/*支持递归加锁*/

pthread_mutex_t mutex_x;

pthread_mutexattr_t attr;

pthread_mutexattr_init(&attr);

pthread_mutexattr_settype(&attr,PTHREAD_MUTEX_RECURSIVE_NP);

pthread_mutex_init(&mutex_x,&attr);

pthread_mutex_lock(&mutex_x);

pthread_mutex_lock(&mutex_x);

//CODE

pthread_mutex_unlock(&mutex_x);

pthread_mutex_unlock(&mutex_x);
