info-xref-all-info-files

info-xref-all-info-files is a compiled Lisp function in `info-xref.el'.

(info-xref-all-info-files)

Return a list of all available info files.
Only top level files are returned, subfiles are excluded.

Since info files don't have to have a .info suffix, all files in
the relevant directories are considered, which might mean a lot
of extraneous things if for instance a source code directory is
in the path.
