LnkAppend

[RPC]

Does lnkappend work by appending a list to a list (so list a b c and lnkappend (list 123)) => (1 2 3 '(abc)) OR does it work like union and return '(1 2 3 a b c)?

It works as an append. The main thing about all the lnk* functions is that they operate in place, not returning the new list. So, an example:

Code: Select all

(setq myList (list 1 2 3))
(lnkAppend myList 4)
;; myList is now '(1 2 3 4)
(lnkAppend myList (list 5 6))
;; myList is now '(1 2 3 4 (5 6))

For your union needs, you need to use `append'. Just remember that it does not operate in place, but rather returns the new list, like so:

Code: Select all

(setq myList (list 1 2 3))
(setq myList (append myList (list 4 5 6))
;; myList is now '(1 2 3 4 5 6)

Hope that helps .]

Thanks alterecco :3
I had assumed that lnkappend worked as #1 and not as union but I wanted to make sure >.<
