C語言筆記 互斥量與讀寫鎖

頭文件

#include <pthread.h>

互斥量初始化與銷燬

int pthread_mutex_init(pthread_mutex_t *restrict mutex, const pthread_mutexattr_t *restrict attr);
int pthread_mutex_destroy(pthread_mutex_t *mutex);

簡單的使用可以使用默認的屬性初始化互斥量，函數的後一個參數設置爲NULL即可。

互斥量加鎖解鎖

int pthread_mutex_lock(pthread_mutex_t *mutex);
int pthread_mutex_unlock(pthreadd_mutex_t *mutex);

讀寫鎖初始化與銷燬

int pthread_rwlock_init(pthread_rwlock_t *restrict rwlock, const pthread_rwlockattr_t *restrict attr);
int pthread_rwlock_destroy(pthread_rwlock_t *rwlock);

讀寫鎖加鎖解鎖

int pthread_rwlock_rdlock(pthread_rwlock_t *rwlock);
int pthread_rwlock_wrlock(pthread_rwlock_t *rwlock);
int pthread_rwlock_unlock(pthread_rwlock_t *rwlock);

自旋鎖

int pthread_spin_init(pthread_spinlock_t *lock, int pshared);
int pthread_spin_destroy(pthread_spinlock_t *lock);

int pthread_spin_lock(pthread_spinlock_t *lock);
int pthread_spin_trylock(pthread_spinlock_t *lock);
int pthread_spin_unlock(pthread_spinlock_t *lock);
