函数原型:int pthread_mutex_init(pthread_mutex_t *restrict mutex,const pthread_mutexattr_t *restrict attr); pthread_mutex_t mutex = PTHREAD_MUTEX_INITIALIZER; pthread_mutex_init()函数是以动态方式创建互斥锁的,参数attr指定了新建互斥锁的属性。如果参数attr为空,则使用默认的互斥锁属性,默认属性为快速互...
int pthread_mutex_trylock(pthread_mutex_t *mutex); 函数pthread_mutex_trylock会尝试对互斥量加锁,如果该互斥量已经被锁住,函数调用失败,返回EBUSY,否则加锁成功返回0,线程不会被阻塞。 intpthread_mutex_timedlock(pthread_mutex_t*restrict mutex,conststruct timesec*restrict tsptr); pthread_mutex_timedlock函数...
pthread_mutex_t mutex=PTHREAD_MUTEX_INITIALIZER; 在LinuxThreads实现中,pthread_mutex_t是一个结构,而PTHREAD_MUTEX_INITIALIZER则是一个结构常量。 动态方式是采用pthread_mutex_init()函数来初始化互斥锁,API定义如下: int pthread_mutex_init(pthread_mutex_t *mutex, const pthread_mutexattr_t *mutexattr) 其...
