    :echo getloclist(3, {'winid' : 0}).winid

    " get the location list window buffer number of the third window

							*setqflist-examples*
The |setqflist()| and |setloclist()| functions can be used to set the various
attributes of a quickfix and location list respectively. Some examples for
using these functions are below:
>
    " create an empty quickfix list with a title and a context
    :let t = 'Search results'
    :let c = {'cmd' : 'grep'}
    :call setqflist([], ' ', {'title' : t, 'context' : c})

    " set the title of the current quickfix list
    :call setqflist([], 'a', {'title' : 'Mytitle'})

    " change the current entry in the list specified by an identifier
    :call setqflist([], 'a', {'id' : qfid, 'idx' : 10})

    " set the context of a quickfix list specified by an identifier
    :call setqflist([], 'a', {'id' : qfid, 'context' : {'val' : 100}})

    " create a new quickfix list from a command output
    :call setqflist([], ' ', {'lines' : systemlist('grep -Hn main *.c')})

    " parse text using a custom efm and add to a particular quickfix list
    :call setqflist([], 'a', {'id' : qfid,
		\ 'lines' : ["a.c#10#L10", "b.c#20#L20"], 'efm':'%f#%l#%m'})

    " add items to the quickfix list specified by an identifier
    :let newItems = [{'filename' : 'a.txt', 'lnum' : 10, 'text' : "Apple"},
		    \ {'filename' : 'b.txt', 'lnum' : 20, 'text' : "Orange"}]
    :call setqflist([], 'a', {'id' : qfid, 'items' : newItems})

    " empty a quickfix list specified by an identifier
    :call setqflist([], 'r', {'id' : qfid, 'items' : []})

    " free all the quickfix lists in the stack
    :call setqflist([], 'f')

    " set the title of the fourth quickfix list
    :call setqflist([], 'a', {'nr' : 4, 'title' : 'SomeTitle'})

    " create a new quickfix list at the end of the stack
    :call setqflist([], ' ', {'nr' : '$',
			\ 'lines' : systemlist('grep -Hn class *.java')})

    " create a new location list from a command output
    :call setloclist(0, [], ' ', {'lines' : systemlist('grep -Hn main *.c')})

    " replace the location list entries for the third window
    :call setloclist(3, [], 'r', {'items' : newItems})

3. Using more than one list of errors			*quickfix-error-lists*

So far it has been assumed that there is only one list of errors.  Actually
there can be multiple used lists that are remembered; see 'chistory' and
'lhistory'.
When starting a new list, the previous ones are automatically kept.  Two
commands can be used to access older error lists.  They set one of the
existing error lists as the current one.

						*:colder* *:col* *E380*
:col[der] [count]	Go to older error list.  When [count] is given, do
			this [count] times.  When already at the oldest error
			list, an error message is given.

						*:lolder* *:lol*
:lol[der] [count]	Same as `:colder`, except use the location list for
			the current window instead of the quickfix list.

						*:cnewer* *:cnew* *E381*
:cnew[er] [count]	Go to newer error list.  When [count] is given, do
			this [count] times.  When already at the newest error
			list, an error message is given.

						*:lnewer* *:lnew*
:lnew[er] [count]	Same as `:cnewer`, except use the location list for
			the current window instead of the quickfix list.

						*:chistory* *:chi*
:[count]chi[story]	Show the list of error lists.  The current list is
			marked with ">".  The output looks like: >
			  error list 1 of 3; 43 errors   :make
			> error list 2 of 3; 0 errors    :helpgrep tag
			  error list 3 of 3; 15 errors   :grep ex_help *.c
<
			When [count] is given, then the count'th quickfix
			list is made the current list. Example: >
				" Make the 4th quickfix list
