C++ (Cpp) ATOMIC_HASH Examples

Example #1

int __atomic_add_return(int i, atomic_t *v)
{
	int ret;
	unsigned long flags;
	spin_lock_irqsave(ATOMIC_HASH(v), flags);

	ret = (v->counter += i);

	spin_unlock_irqrestore(ATOMIC_HASH(v), flags);
	return ret;
}

Example #2

File: mutex.c Project: Ga-vin/apache

static APR_INLINE apr_thread_mutex_t *mutex_hash(volatile apr_uint32_t *mem)
{
    apr_thread_mutex_t *mutex = hash_mutex[ATOMIC_HASH(mem)];

    if (apr_thread_mutex_lock(mutex) != APR_SUCCESS) {
        abort();
    }

    return mutex;
