Doubly Linked List Library

A doubly linked list library in C that can accept any data type that is wrapped within a struct and provides a set of requested methods.
It is implemented with opaque pointers for abstraction and security.

Introducing version 2.1 - Iterators

A brief changelog

1. Added support for iterators (look below for more info)
2. Changed ugly dllistptr to a more [user and C]-friendly naming convention, that is list_t (important)
3. Renamed the library files to a more C-like naming convention, like this: doubly_linked_list_adt.c/h
4. Updated demo to include some of the iterator functionality
5. This version was extensively tested with a multithreaded project, that used the list with about 10 datatypes
6. Added a copy-constructor-like method to copy lists
7. Binary search to access find the associated element in the list of iterators
8. In big programs, compile with -O2 or -O3 to see the magic

Changelog

[*] 2.1 - Upgraded search/ access of iterators (from linear to binary search)
[*] 2.0 - Iterators support
[*] 1.0 - Initial release

##Getting started with the library

1. You will need to copy the doubly_linked_list_adt.c and doubly_linked_list_adt.h files to your project and include the header file to your source code

2. Implement the required functions for the library, stated here, in a source file and provide the prototypes in a header file

3. To use a list, declare a list_t variable and pass it to dll_init function

4. Declare and prepare a Datatype dummy variable, allocate it with your function and call any of the dll_insert* variants (depending on your needs)

   N.B.: To add other elements to the list, don't allocate an object again, just update the previous one to insert it

5. When you're done with your list, only then you call the free_datatype function you've written

6. Finally, pass the list_t variable to dll_destroy function to deallocate the memory needed
