+

+- Returns an empty table if the quest log is empty or contains more than 256 entries.
 
 **Examples:**
-```
-/run local t=GetQuestLogQuestIds(); local i; for i=1,table.getn(t) do print(t[i]) end
+```lua
+-- Print all current quest IDs (reusable ref)
+local t = GetQuestLogQuestIds()
+for i = 1, table.getn(t) do
+    print(t[i])
+end
+
+-- Get a snapshot copy (safe to store across calls)
+local snapshot = GetQuestLogQuestIds(1)
 ```
