iterate to next entry in hash table
ck_ht_next() function will increment the iterator
object pointed to by iterator to point to the next
non-empty hash table entry. If
true then the pointer pointed to by
entry is initialized to the current hash table entry
pointed to by the iterator object.
It is expected that iterator has been
initialized using the
function or statically initialized using
then the object pointed to by entry points to a valid
hash table entry. If
false then value of the object pointed to by
entry is undefined.
