本文详细介绍了多种并发控制原语，包括互斥锁、读写锁、条件变量、自旋锁、屏障及信号量等，并提供了每个原语的初始化、销毁、锁定、解锁等操作的函数说明。

互斥锁
int pthread_mutex_init(pthread_mutex_t *restrict, const pthread_mutexattr_t *restrict);
int pthread_mutex_destroy(pthread_mutex_t *);
int pthread_mutex_lock(pthread_mutex_t *);
int pthread_mutex_trylock(pthread_mutex_t *);
int pthread_mutex_unlock(pthread_mutex_t *);

读写锁
int pthread_rwlock_init(pthread_rwlock_t *restrict, const pthread_rwlockattr_t *restrict);
int pthread_rwlock_destroy(pthread_rwlock_t *);
int pthread_rwlock_rdlock(pthread_rwlock_t *);
int pthread_rwlock_wrlock(pthread_rwlock_t *);
int pthread_rwlock_tryrdlock(pthread_rwlock_t *);
int pthread_rwlock_trywrlock(pthread_rwlock_t *);
int pthread_rwlock_unlock(pthread_rwlock_t *);

条件变量
int pthread_cond_init(pthread_cond_t *restrict, const pthread_condattr_t *restrict);
int pthread_cond_destroy(pthread_cond_t *);
int pthread_cond_wait(pthread_cond_t *restrict, pthread_mutex_t *restrict);
int pthread_cond_signal(pthread_cond_t *);
int pthread_cond_broadcast(pthread_cond_t *);

自旋锁
int pthread_spin_init(pthread_spinlock_t *, int);
int pthread_spin_destroy(pthread_spinlock_t *);
int pthread_spin_lock(pthread_spinlock_t *);
int pthread_spin_trylock(pthread_spinlock_t *);
int pthread_spin_unlock(pthread_spinlock_t *);

屏障
int pthread_barrier_init(pthread_barrier_t *restrict, const pthread_barrierattr_t *restrict, unsigned);
int pthread_barrier_destroy(pthread_barrier_t *);
int pthread_barrier_wait(pthread_barrier_t *);

信号量
int sem_init(sem_t *, int, unsigned);
int sem_destroy(sem_t *);
int sem_wait(sem_t *);
int sem_trywait(sem_t *);
int sem_post(sem_t *);
