40.1. Overview. For a general description of the L3 forwarding applications capabilities please refer to the documentation of the standard application in L3 Forwarding Sample Application. The performance thread sample application differs from the standard L3 forwarding example in that it divides the TX and RX processing between different threads, and makes it possible to assign individual.

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 (). Creating and Destroying Condition Variables.

STANDARDS The pthread library conforms to IEEE Std 1003.1-2001 ("POSIX.1"). CAVEATS Due to limitations in the current pthread implementation, makecontext(3) and sigaltstack(2) should not be used in programs which link against the pthread library (whether threads are used or not). NetBSD 9.99 November 22, 2016 NetBSD 9.99. 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 ().
Pthread_setschedprio (3) - Linux Man Pages.
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. Pthread_spin_init. The pthread_spin_init function shall allocate any resources required to use the spin lock referenced by lock and initialize the lock to an unlocked state.
Pthread Interfaces — NuttX latest documentation.
The interfaces for spin locks are similar to those for mutexes, making it relatively easy to replace one with the other. We can initialize a spin lock with the pthread_spin_init function. To deinitialize a spin lock, we can call the pthread_spin_destroy function.

Pthread_spinlock_t的特点是高效。但是如果一个线程在获得spinlock的时候陷入操作系统内核（比如时间片超时、缺页异常）会怎么样呢？另外一个线程在获取spinlock的时候会一直占用cpu。会有一个瞬间的cpu占用率高峰？这个高峰的持续时间取决于另外一个线程何时从内核返回。. 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.

スピンロックの初期化. スピンロックを使用するために必要なリソースを割り当て、ロックをロック解除状態に初期化するには、pthread_spin_init(3C) 関数を使用します。 pthread_spin_init() の構文 int pthread_spin_init(pthread_spinlock_t *lock, int pshared); #include <pthread.h> pthread_spinlock_t lock; int pshared; int ret; /* initialize.
Nptl - Glibc source code (glibc-2.35.9000) - Bootlin.
The pthread_spin_init () function allocates any resources required for the use of the spin lock referred to by lock and initializes the lock to be in the unlocked state. The pshared argument must have one of the following values: PTHREAD_PROCESS_PRIVATE.
Pthread.3.
If successful, pthread_mutex_init() returns 0, and the state of the mutex becomes initialized and unlocked. If unsuccessful, pthread_mutex_init() returns -1. int pthread_mutex_lock(pthread_mutex_t *mutex) Locks a mutex object, which identifies a mutex. If the mutex is already locked by another thread, the thread waits for the mutex to become. If the pthread_spin_init() function fails, the lock is not initialized and the contents of lock are undefined. Only the object referenced by lock can be used for performing synchronization. The result of referring to copies of that object in calls to pthread_spin_destroy() , pthread_spin_lock (3C) , pthread_spin_trylock (3C) , or pthread_spin. The pshared argument must have one of the following values: PTHREAD_PROCESS_PRIVATE The spin lock is to be operated on only by threads in the same process as the thread that calls pthread_spin_init (). (Attempting to share the spin lock between processes results in undefined behavior.).

INLINE int ptw32_spinlock_check_need_init (pthread_spinlock_t * lock) { int result = 0; /* * The following guarded test is specifically for statically * initialised spinlocks (via PTHREAD_SPINLOCK_INITIALIZER). The call pthread_spin_init(). initializes a spin lock. A spin lock can be shared between processes or private to the process that created it. By passing the value PTHREAD_PROCESS_PRIVATE to the pthread_spin_init(), a spin lock is not shareable. To make it sharable, we need to pass the value PTHREAD_PROCESS_SHARED. The default is set to be private. This library is usually included automatically. Description: The pthread_spin_init () function allocates the resources required for the thread spinlock spinner, and initializes spinner to an unlocked state. Any thread that can access the memory where spinner is allocated can operate on the spinlock.
