That's correct. To check the alignment you would have to look at the actual pointer. I would suggest using the existing macros to handle alignment. Hm, though the only one I see offhand which is relevant is the moderately silly PointerIsAligned(). Still it would make the code clearer even if it's pretty simple. Incidentally, the char foo[4] = {' ',' ',' ',' '} suggestion is, I think, bogus. There would be no alignment guarantee on that array. Personally I'm find with 0x20202020 with a comment explaining what it is. -- greg http://mit.edu/~gsstark/resume.pdf -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
