Pthread_spin_lock函数
WebCalling pthread_spin_lock() on a lock that is already held by the caller or a lock that has not been initialized with pthread_spin_init(3) results in undefined behavior. The pthread_spin_trylock () function is like pthread_spin_lock (), except that if the spin lock referred to by lock is currently locked, then, instead of spinning, the call ... http://cxd2014.github.io/2024/12/05/pthread/

WebDec 5, 2024 · 对互斥量进行加锁,需要调用pthread_mutex_lock函数,如果互斥量已经上锁调用线程将阻塞直到互斥量被解锁。对互斥量解锁,需要调用pthread_mutex_unlock函数。如果线程不希望被阻塞,他可以使用pthread_mutex_trylock函数尝试对互斥量进行加锁。如果此时互斥量处于未锁住状态,那么pthread_mutex_trylock将锁住 ... Web可以使用 pthread_mutex_trylock() 函数。 这个函数和 pthread_mutex_lock() 用法一样,只不过当请求的锁正在被占用的时候, 不会进入阻塞状态,而是立刻返回,并返回一个错误 …

WebPOSIX.1 specifies a set of interfaces (functions, header files) for threaded programming commonly known as POSIX threads, or Pthreads. A single process can contain multiple threads, all of which are executing the same program. These threads share the same global memory (data and heap segments), but each thread has its own stack (automatic ...
