Passing hash-table or alist to a function

Passing hash-table or alist to a function

[Heime]

Have mode the following function

(defvar xiakos-fpln (make-hash-table :test 'equal)
  "Hash table storing paths for different xiakos components.")

Can one distinguish passing a hash-table or an alist to a 
function, how ?

Try:

(setq ht (make-hash-table))
(puthash :key1 :val1 ht)
(puthash :key2 :val2 ht)
ht

(setq al '((:key1 . :val1) (:key2 . :val2)))
al

(hash-table-p ht)
(hash-table-p al)

Read the elisp hash table docs. There is one function made exactly
for that.
