Pthread_spin_unlock (3p) - Linux Man Pages - SysTutorials.

Pthreads on Microsoft Windows. An extremely common API used for developing parallel programs is the Posix Threads API (pthreads). The API contains many synchronization primitives that allow threaded code to be efficiently written. Unfortunately, Microsoft Windows does not support this interface as-is. Int pthread_spin_init (pthread_spinlock_t * lock, int pshared); Description The pthread_spin_destroy () function shall destroy the spin lock referenced by lock and release any resources used by the lock. The effect of subsequent use of the lock is undefined until the lock is reinitialized by another call to pthread_spin_init (). By default, a Pthreads mutex is not recursive, which means that a thread should not try to lock a mutex that it already owns. However, the POSIX 1003.1 2001 standard allows a mutex's type attribute to be set to recursive: pthread_mutex_t mutex; pthread_mutexattr_t mutexAttribute; int status = pthread_mutexattr_init (&mutexAttribute).

The pthread_spin_init() function may fail if: [EINVAL] The lock parameter was NULL or the pshared parameter was neither PTHREAD_PROCESS_SHARED nor PTHREAD_PROCESS_PRIVATE. The pthread_spin_destroy () function may fail if: [EBUSY] The system has detected an attempt to destroy the object referenced by lock while it is locked.

Pthread_spin_unlock.S source code [glibc/sysdeps/i386/nptl/pthread_spin.

The pthread_spin_init() function allocates the resources required to use the spin lock pointed to by the lock argument and initializes the lock to an unlocked state. When the value of pshared is PTHREAD_PROCESS_SHARED , the spin lock can be operated upon by any thread that has access to the memory where the spin lock is allocated, even if it is. All the times, I think TBB library is the best tool in multi-threading programing. But today, I found pthread spin_lock is 28% faster than tbb::spin_mutex, I am confused. I check the source code between pthread spin_lock and tbb::spin_mutex: // the following is pthread spin_lock. // glibc-2.8nptlsysdepsi386pthread_spin_lock.c. int.

Pthread_spin_init() Initialize a spinlock object. pthread_spin_destroy() Destroy a spinlock object. pthread_spin_lock() Lock a spinlock object. pthread_spin_trylock() Attempt to lock a spinlock without blocking. pthread_spin_unlock() Unlock a spinlock object. Thread Routines. The functions available are as follows: pthread_create() Create a new. The results are undefined if the pthread_spin_destroy subroutine is called when a thread holds the lock, or if this function is called with an uninitialized thread spin lock. The pthread_spin_init subroutine allocates any resources required to use the spin lock referenced by lock and initializes the lock to an unlocked state.

Man pthread_spin_destroy (1): destroy or initialize a.

The pthread_spin_initfunction shall allocate any resources required to use the spin lock referenced by lockand initialize the lock to an unlocked state. Pthreads-w32supports single and multiple processor systems as well as process CPU affinity masking by checking the mask when the spin lock is initialized. If the process is using only a single. Calling 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.

The pthread_mutexattr_init () function shall initialize a mutex attributes object attr with the default value for all of the attributes defined by the implementation. Results are undefined if pthread_mutexattr_init () is called specifying an already initialized attr attributes object. After a mutex attributes object has been used to initialize. Pthread_mutex_t m = PTHREAD_MUTEX_INITIALIZER; // declare/init a lock pthread_cond_t c = PTHREAD_COND_INITIALIZER; // declare/init a CV a condition variable (CV) is: - queue of waiting threads a single lock is associated with a CV (sometimes N CVs per lock) wait (cond_t *cv, mutex_t *lock) - assumes the lock is held when wait() is called) - puts caller to sleep + releases the lock (atomically).

* (including negligence or otherwise) arising in any way out of the use. * of this software, even if advised of the possibility of such damage. */. The pthread_mutex_init () function initializes the specified mutex. If attr is non- NULL, the attributes specified are used to initialize the mutex. If the attribute object is modified later, the mutex's attributes are not affected. If attr is NULL, the mutex is initialized with default attributes, as specified for pthread_mutexattr_init ().

This article will explain several methods of how to use mutex lock in C. Use the pthread_mutex_t Type and pthread_mutex_lock Function to Guard the Critical Section of the Code. Threads share address spaces, which implies that modifications to the shared data like global variables must be synchronized; otherwise, there will be incorrect.

DESCRIPTION The pthread_spin_init () function is used to initialize a spin lock. In the NetBSD implementation the pshared parameter is currently unused and all spin locks exhibit the PTHREAD_PROCESS_SHARED property, implying that all spin locks may be accessed by threads of multiple processes.
