Dear All

What is padding granularity ? Please give me the basic concept
of this.

It isn't to my knowledge an established term in the context of the C
language, so it might help if you give some context.

"Padding" is space that the compiler can put between (strictly after)
structure members. This is done to make sure that the following member is
aligned appropriately. This is done for efficiency reasons, for example
the architecture may not directly support unaligned access to certain data
types (e.g. a "word" might have to be aligned on a "word" boundary).

"Padding granularity" might relate to this concept of alignment. However a
quick search on Google didn't come up with anything specifically related
to this or C in general.
