Module Name:

    inf.h

Abstract:

    Declares interface for INF wrapper routines.  These routines simplify
    access of INFs by wrapping the setup APIs with routines that use
    pools or grow buffers.

    The INF wrapper routines also implement append and replace capabilities,
    so any INF used by the Win9x upgrade can be appended in the future, or
    completely replaced.
