doubly linked list library wanted

[Phil Howard KA9WGN]

I would like to find C sources for a library or example working code to
manipulate doubly linked lists.  In particular, basic operations of
    insert on front
    insert on back
    delete from front
    delete from back
    delete element
would be useful.

Mostly this is a study of the diversity of actually implemented methods
of working with doubly linked lists.  For instance I would like to see
how solutions have be done for things like:
    elements on more than one list
        fixed number of lists
        dynamic number of lists
    variations on first/last element references
    variations on anchor references
    delta pointer links

I will be checking major anonymous FTP sites for file names that seem to be
obvious to me as being sources of doubly linked list, such as by searching
for strings in the names like "doubl", etc.  If you know of such a package
but it is very obvious by its filename, I'll probably run across it.  But
I would certainly like to see other sources.

If you want to mail sources, please tar, compress, and (uu|xx)encode, and
mail to phil at ux1.cso.uiuc.edu.  If the size is larger than mailable in a
total under 100K, please contact me and let me know if you can FTP.

Thanks.
