I have not looked at the respective code yet (short of time right now) but the names of those functions suggests that they might be looking at those variables not as much as Scheme values but rather as internals related to the operation of the Scheme interpreter. If that guess is correct, using SCM_UNPACK would likely better convey the kind of action here (and allow access as a bit pattern/integer/whatever). -- David Kastrup _______________________________________________ lilypond-devel mailing list lilypond-devel@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-devel
