C++ (Cpp) deque_front Examples

Example #1

File: cstl_queue.c Project: cffyh/libcstl

/**
 * Access queue front data.
 */
void* queue_front(const queue_t* cpque_queue)
{
    assert(cpque_queue != NULL);

#ifdef CSTL_QUEUE_LIST_SEQUENCE
    return list_front(&cpque_queue->_t_sequence);
#else
    return deque_front(&cpque_queue->_t_sequence);
#endif
}

Example #2

File: deque.c Project: vaughan0/vlib

static int deque_basic() {
  Deque d[1];
  deque_init(d, sizeof(int), 10);

  *(int*)deque_pushback(d) = 2;
  *(int*)deque_pushback(d) = 3;
  *(int*)deque_pushfront(d) = 1;
  *(int*)deque_pushback(d) = 4;
  *(int*)deque_pushfront(d) = 0;

  for (int i = 0; i <= 4; i++) {
    int val = *(int*)deque_front(d);
    deque_popfront(d);
    assertEqual(i, val);
    assertEqual(4-i, deque_size(d));
  }
