Message-ID: <19880926174755.9.RWS@KILLINGTON.LCS.MIT.EDU> Date: 26 Sep 88 17:47:00 GMT References: <394@quintus.UUCP> Sender: daemon@bloom-beacon.MIT.EDU Organization: The Internet Lines: 19 Date: 13 Sep 88 20:06:46 GMT From: quintus!pds@unix.sri.com (Peter Schachte) What parts of the X.h include file can one assume won't change, either over time, or between vendors? Basically all of it. (Well, X_PROTOCOL_REVISION might increment ...) Is None always going to be 0? Yes. Or is the whole file just a bunch of convenient defines for constants that are part of the protocol, and will never change? True of the numeric constants. The typedefs are specific to C, but there should be no reason to change them either.
