Hi ... sorry I could not ask very well, what I wanted to. I have a piece of
code that ASSUMES that the above structure is padded (and I do not want to
change that code). So how can I make sure that this structure is always padded
(Is there any other way apart from adding explicit padding field?)
So like we have a "packed" gcc attribute, do we have a "padded" gcc attribute
or something like that (that ensures that gcc will always pad this structure.).
Thanks,
Rajat
