Module Name:
SectionExtraction.c
Abstract:
Section Extraction Protocol implementation.
Stream database is implemented as a linked list of section streams,
where each stream contains a linked list of children, which may be leaves or
encapsulations.
Children that are encapsulations generate new stream entries
when they are created. Streams can also be created by calls to
SEP->OpenSectionStream().
The database is only created far enough to return the requested data from
any given stream, or to determine that the requested data is not found.
If a GUIDed encapsulation is encountered, there are three possiblilites.
1) A support protocol is found, in which the stream is simply processed with
the support protocol.
2) A support protocol is not found, but the data is available to be read
without processing. In this case, the database is built up through the
recursions to return the data, and a RPN event is set that will enable
the stream in question to be refreshed if and when the required section
extraction protocol is published.This insures the AuthenticationStatus
does not become stale in the cache.
3) A support protocol is not found, and the data is not available to be read
without it. This results in EFI_PROTOCOL_ERROR.
