A free list (or freelist) is a data structure used in a scheme for dynamic memory allocation. It operates by connecting unallocated regions of memory together in a linked list, using the first word of each unallocated region as a pointer to the next. It is most suitable for allocating from a memory pool, where all objects have the same size ...
A linked list in an inconsistent state, caused by application of the naive lock-free deletion algorithm. Dotted lines are links that exist in intermediate states; solid lines represent the final state. Deletion of the node holding a has executed simultaneously with insertion of b after a, causing the insertion to be undone.
In a doubly linked list, one can insert or delete a node in a constant number of operations given only that node's address. To do the same in a singly linked list, one must have the address of the pointer to that node, which is either the handle for the whole list (in case of the first node) or the link field in the previous node. Some ...
libHaru is a free, open-source, cross platform library for generating PDF files for applications written in C or C++. [1] [2] [3] It is not intended for reading and editing existing PDF files. It supports the following features: Generating PDF files with lines, text, images. Outline, text annotation, link annotation. Compressing document with ...
A linked list is a collection of structures ordered not by their physical placement in memory but by logical links that are stored as part of the data in the structure itself. It is not necessary that it should be stored in the adjacent memory locations. Every structure has a data field and an address field.
The list starts out with a single node, the sentinel node which has the next and previous pointers point to itself. This condition determines if the list is empty. In a non-empty list, the sentinel node's next pointer gives the head of the list, and the previous pointer gives the tail of the list.

A singly-linked list structure, implementing a list with three integer elements. The term list is also used for several concrete data structures that can be used to implement abstract lists, especially linked lists and arrays. In some contexts, such as in Lisp programming, the term list may refer specifically to a linked list rather than an array.
