[erlang-questions] gen_tcp question

I was not disagreeing with you that it should be documented. I
suppose I was making an observation on human (and corporate) behaviour.
Personally I am happy to derive an intent from the combination of the
existing documentation and my own testing. If it ended up not working
as implied by the documentation then I would have had no hesitation
to raise a trouble ticket using the commercial support option and
blag it. Others are not happy to rely on this level of assumption so
it should of course be documented.
To the point in hand:
I am sure Tony could make some statement of what it was supposed to
do when he wrote it, but that is surely not enough.
Ericsson might have a plan to change the undocumented behaviour so it
only works for packets without an F in the length in an unspecified
So, only Ericsson can make any statement of what the program is
supposed to do now and in the future. And that place is the
documentation and any support contracts you might have with them.
