Changing the data structure will require that PHP be running as the same user that created the queue, owns the queue (as determined by the existing msg_perm.xxx fields), or be running with root privileges.
allows you to change the values of the msg_perm.uid, msg_perm.gid, msg_perm.mode and msg_qbytes fields of the underlying message queue data structure.

 Java Data Structures (2nd edition) - END OF THE WORLD PRODUCTION, LLC
This section will show you how you can convert some data structures previously devised, to implement a stack and a queue, with almost no creativity (by simply reusing the old source).
Trees are node based data structures, meaning that they're made out of small parts called nodes.
Node based data structures provide for dynamic growing and shrinking, and are the key to some complex algorithms (as you'll see later).

 Multimap or other ?
But a smarter solution would use two data structures, one for your priority queue and one for checking duplicates, such as a set:
Well, the thing is that I need the association with another data structure for a given key, but the key being needed for sorting.
I need to create a stack with a key and for each key one or more instances of a data structure associated.

The ordered set data structure is described on Page 727 of the Cheriton-Tarjan paper and how it can be used to implement a priority queue of edges so that the desired running time is achieved, is described on Page 733 on the Cheriton-Tarjan paper.
You can choose to implement a priority queue using either of these two data structures, however your implementation might be simpler if you use ordered sets.
\end{itemize} In summary, I recommend: (a) using the uniform tree selection rule for selecting a tree from $F$ (b) implementing $F$ using the disjoint set data structure described in Tarjan's book and (c) using the ordered set data structure for implementing priority queues containing the edges incident on each tree in $F$.

A multimap is a similar data structure, whose key difference is that it allows more than one association to contain a particular key.
I'd like your Multimap to be well-behaved, just as our Queue class in lecture was, so that it can be declared as a local variable, allocated and deallocated dynamically with new and delete, passed by value, and used in an assignment statement.

A data structure is a way of organizing data that considers not only the items stored, but also their relationship to each other.
Advance knowledge about the relationship between data items allows designing of efficient algorithms for the manipulation of data.

 Abstract Data Types
Lars H: Given a range of implementations of a data structure, the right question is probably rather what the computational complexities of standard operations are for these implementations.
At the level of the tcl language string (together with all the commands which manipulate strings) is an abstract data type, since it defines a type of data which you can operate on using the string interface commands, but you can't tell from the tcl language whether it's null-terminated or length-prepended.
Array is an abstract data type, since you can access its contents with [array get] or using (), but you can't tinker with the hash collision tables which underly the array representation.

However, to insert F into the queue, q.rear must be increased by 1 to 5 and q.items[5] must be set to the value F. But q.items is an array of only five elements, so that the insertion cannot be made.

Since we need to find the nearest event in the future among those waiting to be processed, a priority queue is the natural data structure to use to hold the events.
Otherwise, in either mode, an entry is made in the table with n1 as the key and (n2, t) as the associated data, and another entry with n2 as the key and (n1, t) as the associated data.
The key of an entry in the table is the calling phone number and the associated data is the called number and the time the call started.

 What is an "Abstract Data Type"?
Concerning the ADT, back in high school days (late 80's early 90's) ADT was always a conceptual structure only, like a stack/heap/queue.
The data type is a stack, but it isn't a primitave data type.
The most common ADT would be a stack, heap or queue, which can be implemented in an OOP manner or a procedural manner in just about (if not all) languages.

 The Priority Queue Operations
The priority queue data type is built on top of a container class, which is the structure actually used to maintain the values in the collection.
Because the priority queue data structure does not itself know how to construct iterators, very few of the algorithms noted in Chapter 13 can be used with priority queues.
Instead of iterating over values, a typical algorithm that uses a priority queue constructs a loop, which repeatedly pulls values from the structure (using the

 Three Fastest Shortest Path Algorithms on Real Road Networks: Data Structures and Procedures : JGIDA vol.1, no.1, pp. 69-82
The deque and two queue data structures described in the next section are particular types of priority queues which are related to the graph growth algorithm implemented with two queues.
The bucket data structure is described in detail in Section 5 because it is related to two of the three recommended algorithms, namely, the approximate and double bucket implementations of the Dijkstra algorithms.
Pape (1974) used a data structure called deque (Q) to maintain the first set of nodes in Q. A deque is illustrated in Figure 1 (Pallottino 1984, p.261).

The data structures, stack and queue, are not built into Logo; the singly and doubly linked lists as taught in data structures courses and implemented in Pascal are not the same as the list in Logo.
The modified data structure should be returned using "call by binding", the Logo simulation of pass by reference.
Therefore, as with any language, if you have an algorithm that utilizes a data structure that is not built in, you must create that data structure from the primitives of the language.

 Data abstraction
Nothing prevents accidental use with the wrong instance of a data structure, so that an array representing a first in first out queue could accidentally be used by the push operation intended for a similar array used to represent a stack.
Object based abstraction says that the definition of a data structure and of the operations upon it should be as a single unit.
Data abstraction with conventional imperative languages, like C, lets us define operations such as insertion and deletion for lists within the body of a procedure and then to program without regard to how they are achieved internally.

 Priority Queues
Bounded height priority queues are useful data structures in practice, but they do not have good worst-case performance bounds when arbitrary insertions and deletions are permitted.
Bare bones implementations in C and Pascal of the basic priority queue data structures appear in [GBY91].
Bounded height priority queue - This array-based data structure permits constant-time insertion and find-min operations whenever the range of possible key values is limited.

 Queue - Wikipedia, the free encyclopedia
For a data structure the executing computer will eventually run out of memory, thus limiting the queue size.
The Oroogu programming language relies on queues as its only data structure.

 The priority queue Data Abstraction
The data structure is not a queue in the sense that we used the term in Chapter 10, since it does not return elements in a strict first-in, first-out sequence.
A priority_queue is a data structure useful in problems where you need to rapidly and repeatedly find and remove the largest element from a collection of values.
For example, it may be necessary to respond rapidly to a key pressed at a terminal before the data is lost when the next key is pressed.
