We should instead use names with exact sizes (16,32,64).

So please tell me why you object so strongly? We have the 16/32/64 bit
names which
are nice but are not expected so folks seem to not use them. I have

people's ignorance is not an excuse for not doing things right.
We'd still be using BYTE, WORD and DWORD otherwise.

I think there is no doubt that we should use the 16/32/64 bit names
if we could start from scratch, and the only reason for not doing
so is avoiding gratuitous changes to existing/stable code.

The case of *to*ll does not apply, in that there is no actual legacy
to adapt to. And btw there is tons of places which use the 16/32/64 bit
names in the filesystem, usb and generic device drivers. In fact,
many more than ntohl/htonl

what he said..

if you want to have ntohll in SCTP then that is your choice, but I think it
should be a local define to be64toh or ntoh64
I do prefer the ntoh64 version but beXXtoh or whatever it looks like others are using is ok to me too since 'net' is a pretty wide definition and not ALL protocols are big endian.
