Yes, see my previous mail.

Muddled in what sense?  (See my comparisons of the names below.)

Unless I've missed something, the situtation seems to be this:
* FreeBSD, NetBSD, and glibc all use *exactly) the same naming
convention, so that they have, e.g., le16toh.
* OpenBSD uses a different convention, so that they have, e.g.,
letoh16.  (This naming convention seems to me a little more sensible.)

I'm guessing that the order of events went like this:

1) OpenBSD provided the first implementation.
2) the other BSDs added the interfaces but changed the naming convention.
3) Ulrich Drepper opted to follow FreeBSD's naming convention (which
seems a reasonable thing to do, given that that is the dominat BSD).

Do you know if that is the order in which things happened?

Cheers,

Michael
