PThread 学习笔记

线程相关函数:

1. pthread 相关函数的头文件: 

    #include <pthread.h>

2. pthread 的创建函数:

    int pthread_create (pthread_t *thread_id, const pthread_attr_t *attributes, void *(*thread_function)(void *), void *arguments);

3. pthread 对应的结束函数:

    int pthread_exit (void *status);

4. 一个线程可以等待另一个线程的结束:

    int pthread_join (pthread_t thread, void **status_ptr);

5. 获取当前线程的 id:

    pthread_t pthread_self ();

6. 比较线程 id:

    int pthread (pthread_t t1, pthread_t t2);

互斥量有两个基本操作:锁与解锁。有五个基本函数用来管理互斥量:

1.  int pthread_mutex_init (pthread_mutex_t *mut, const pthread_mutexattr_t *attr);

2. int pthread_mutex_lock (pthread_mutex_t *mut);

3. int pthread_mutex_unlock (pthread_mutex_t *mut);

4. int pthread_mutex_trylock (pthread_mutex_t *mut);

5. int pthread_mutex_destroy (pthread_mutex_t *mut);

条件变量

1. int pthread_cond_init (pthread_cond_t *cond, pthread_condattr_t *attr);

2. int pthread_cond_wait (pthread_cond_t *cond, pthread_mutex_t *mut);

3. int pthread_cond_signal (pthread_cond_t *cond);

4. int pthread_cond_broadcast (pthread_cond_t *cond);

5. int pthread_cond_timedwait (pthread_cond_t *cond, pthread_mutex_t *mut, const struct timespec *abstime);

6. int pthread_cond_destroy (pthread_cond_t *cond);
