Subject: Re: Alignment of mixed-data type items in properties
Date: Mon, 08 Nov 2010 19:09:49 -1000 [thread overview]
Message-ID: <4CD8D79D.6080708@firmworks.com> (raw)
In-Reply-To: <20101109012845.GC30378@yookeroo>
The reason for not aligning in Open Firmware
property values because I got tired of having
to fix structures that needed different padding
when moving to different systems. I just decided
to dispense with alignment, constructing property
values with serialization functions and reading
them with deserialization functions.
People often get away with structure-based property
access techniques, but the "official model" is based
on a byte stream of concatenated elements with no
internal alignment.
