Nevermind, the standard is a moving target. Sorry. What I quoted was from
draft 5, and I now checked draft 6, and it does not refer to a single
constant "255" anymore. Instead, it refers to HOST_NAME_MAX, which has
the minimum acceptable value 255, but may be unspecified. So, the situation
will be just as with PATH_MAX, you can even get the value with sysconf and
_SC_HOST_NAME_MAX.
Sorry, it really is changing more than I expected. I should wait for the
released standard before making suggestions like that.
Thanks,
Marcus
