(I'm going through old bug reports that unfortunately weren't resolved
at the time.)

I don't think it would be appropriate to add a function like this to the
C level of Emacs, because the use case is very limited.  And I think you
can basically get the same functionality by using the xelb package
(which talks to the X servers from Lisp).

So I'm closing this bug report as a "wontfix".
