Documentation

Function to display a list of search results.

It should accept two arguments: FETCHER and ALIST.

FETCHER is a function of no arguments that returns a list of xref values. It must not depend on the current buffer or selected window.

ALIST can include, but limited to, the following keys:

WINDOW for the window that was selected before the current command was called.

DISPLAY-ACTION indicates where the target location should be displayed. The possible values are nil, window meaning the other window, or frame meaning the other frame.

Probably introduced at or before Emacs version 27.1.
