示例1: enqueue_to_head
//! Add an element to the blocking queue
inline void enqueue_to_head(const T& elem) {
m_mutex.lock();
m_queue.push_front(elem);
// Signal threads waiting on the queue
if (sleeping) m_conditional.signal();
m_mutex.unlock();
}示例2: receive
void receive(procid_t source, blob b) {
mut.lock();
val = b;
valready = true;
cond.signal();
mut.unlock();
}示例3: enqueue_conditional_signal
inline void enqueue_conditional_signal(const T& elem, size_t signal_at_size) {
m_mutex.lock();
m_queue.push_back(elem);
// Signal threads waiting on the queue
if (sleeping && m_queue.size() >= signal_at_size) m_conditional.signal();
m_mutex.unlock();
}示例4: swap
void swap(queue_type &q) {
m_mutex.lock();
q.swap(m_queue);
if (m_queue.empty() && sleeping_on_empty) {
m_empty_conditional.signal();
}

}示例5: post
inline void post() const {
mut.lock();
if (waitercount > 0) {
cond.signal();
}
semvalue++;
mut.unlock();
}示例6: decrement_running_counter
inline void decrement_running_counter() {
// now, a bit of care is needed here
size_t r = threads_running.dec();
if (r == 0) {
join_lock.lock();
if (join_waiting) {

}
}示例7: run
void run (void)
{

if (!thread_running) return;
// join the log rotation thread.
lock.lock();
thread_running = false;
cond.signal();
lock.unlock();
log_rotate_thread.join();
// we will continue logging to the same location, but we will
// delete the symlink
unlink(symlink_name.c_str());
}示例9: make_pair
inline std::pair<T, bool> try_dequeue_in_critical_section() {
T elem = T();
// Wait while the queue is empty and this queue is alive
