What is the best way to distinguish the current buffer is location list or quickfix list?

Question

I have an autocmd, if `ft` is `qf`, it is gonna call some functions to modify the quickfix list by `get/setqflist()` I know there are another pair of functions `get/setloclist()`, to handle the location list. My problem is, how to know if the current buffer is `qf-list` or `location-list` (They both have `filetype` `qf`) so that I know which functions should be called? so far what I can think of is, assume both loc and qf lists are not empty, do some change on qf-list, and compare with current buffer, if the current buffer is changed too, it is qf-list, otherwise it should be location list. Finally roll back the changes. But I feel it is stupid... there should be better way to make the decision. Did I miss some function/flag/variable ?

Accepted Answer

Just for new comers: as of now, there is `getwininfo()` which returns dicts containing key `quickfix` which can be used for the check. Also note the `loclist` key.

Since `getwininfo` returns a list of dict, you may use:

```
getwininfo(win_getid())[0]['quickfix']
```

which is 1 when it is a quickfix or location list window. And

```
getwininfo(win_getid())[0]['loclist']
```

which is 1 only when it is a location list.

In short:

```
 getwininfo() value:  'quickfix'    'loclist' 
------------------------------------------------
quickfix list            1              0
location list            1              1
```
