I would like to know if a linked list list has been implemented in
any GRASS program to date. If anyone knows of such a program, could
you please let me know? Otherwise, does anyone anticipate any
pitfalls in the idea? (in the context of memory allocation and freeing
by G_malloc(), G_realloc() and free().) In fact, I am thinking of a
3-dimentional linked list.
You will find a fair amount of linked list manipulations in r.surf.idw.
Be sure to get the latest copy from ftp moon. free () is an expensive
operation on most platforms; recycling without free () is preferable.
When I minimized the use of free () in r.surf.idw, there was a 15%
improvement in performance.
