You will have to take the return value from get_link_attr_entry_list in
$link_attr_entry_list_ref
or
change the following line to get_link_priority
(get_link_attr_entry_list ($link_id));

The variable declared here is lexically scoped inside this subroutine. The return
value
is also not being used. The reference that you have created will be lost after the
execution
of this subroutine.
