.H and .LIB for MMC classes ?

Hi all

I would like to get the MMC card ID (CID info) with C++. I found some classes
in
SDK document (like TMMCCard and DMMCController), but I can't find the related
.H
(p32mmc.h) and .LIB (epbus.lib) in any Symbian v7.0 SDK.

I know some guys have asked the same question in this and other forums before,
but no any answer is given. I am wondering is it possible that I can get some
offical response from Symbian professionals?

Thanks  in advance.
