PThread learning notes

Thread-related functions:

1. header file of pthread-related functions:

# Include <pthread. h>

2. pthread creation function:

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

3. The ending function corresponding to pthread:

Int pthread_exit (void * status );

4. One thread can wait for the end of another thread:

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

5. Get the id of the current thread:

Pthread_t pthread_self ();

6. Compare thread id:

Int pthread (pthread_t t1, pthread_t t2 );

The mutex has two basic operations: Lock and unlock. There are five basic functions used to manage mutex:

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 );

Condition variable

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 );
