Memory alignment question

Hi All,

I have some question related for memory alignment of the buffer that
is gotten by the driver subclassed from IOBlockStorageDevice.

#1 Is the buffer that is gotten by the driver will always aligned ?
In other words, is it always guaranteed that the buffer parameter of
doAsyncReadWrite or doSyncReadWrite is aligned ?

#2 If #1 is yes, how aligned ? 4Bytes ? 8Byte? more ?

#3 If #1 is no, are there any possilibilty that "Physical is contnue
but logical is segmented" buffer ? Because I need to write a follow-
up routine.


Regards,

Zak
