pthread快速参考

1，Pthread线程控制
int pthread_create(pthread_t *restrict tidp, const pthread_attr_t *restrict attr, void *(*stat_rtn)(void*), void *restrict arg);
int pthread_exit(void *status);
int pthread_cancel(pthread_t thread);
int pthread_join(pthread_t tid, void **tret);
int pthread_cleanup_push(void (*rtn)(void*), void *arg);
int pthread_clean_pop(int execute);
int pthread_equal(pthread_t tid1, pthread_t tid2);
pthread_t pthread_self(void);

2，Pthread提供多种同步机制：
1) Mutex（互斥量）：pthread_mutex_xxx
2) Condition Variable（条件变量）：pthread_con_xxx
3) Read/Write lock（读写锁）：pthread_rwlock_xxx
4) Spin lock（自旋锁）：pthread_spin_xxx

int pthread_rwlock_unlock(pthread_rwlock_t *rwlock);

int pthread_cond_init(pthread_cond_t *restrict cond, const pthread_condattr_t *restrict attr);
int pthread_cond_destroy(pthread_cond_t *cond);
