Regards--PA 解决方案 It appears not to. That''s probably because it should not be neededunless your code is buggy. If your code is standard C, the compilershould have aligned everything nicely for you. However, you didn''tpost the code that creates the unaligned pointer. Also:- - Some CPUs allow unaligned access.- - Some operating systems can transparently handle unaligned access onsystems that don''t support it.- --Roger LeighPrinting on GNU/Linux? http://gimp-print.sourceforge.net/Debian GNU/Linux http://www.debian.org/GPG Public Key: 0x25BFB848.
