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 -- `Rhubarb is no Egyptian god.'
