This file declares the Section Extraction PPI.
|
|
|
|
This PPI is defined in PEI CIS version 0.91. It supports encapsulating sections,
|
|
such as GUIDed sections used to authenticate the file encapsulation of other domain-specific wrapping.

The function is used to retrieve a section from within a section file.
|
|
It will retrieve both encapsulation sections and leaf sections in their entirety,
|
|
exclusive of the section header.
|
|
|
|
@param PeiServices The pointer to the PEI Services Table.
|
|
@param This Indicates the calling context
|
|
@param SectionType The pointer to an EFI_SECTION_TYPE. If
|
|
SectionType == NULL, the contents of the entire
|
|
section are returned in Buffer. If SectionType
|
|
is not NULL, only the requested section is returned.
|
|
@param SectionDefinitionGuid The pointer to an EFI_GUID.
|
|
If SectionType == EFI_SECTION_GUID_DEFINED,
|
|
SectionDefinitionGuid indicates for which section
|
|
GUID to search. If SectionType != EFI_SECTION_GUID_DEFINED,
|
|
SectionDefinitionGuid is unused and is ignored.
|
|
@param SectionInstance If SectionType is not NULL, indicates which
|
|
instance of the requested section type to return.
|
|
@param Buffer The pointer to a pointer to a buffer in which the
|
|
section contents are returned.
|
|
@param BufferSize A pointer to a caller-allocated UINT32. On input,
|
|
*BufferSize indicates the size in bytes of the
|
|
memory region pointed to by Buffer. On output,
|
|
*BufferSize contains the number of bytes required
|
|
to read the section.
|
|
@param AuthenticationStatus A pointer to a caller-allocated UINT32 in
|
|
which any metadata from encapsulating GUID-defined
|
|
sections is returned.
|
|
|
|
@retval EFI_SUCCESS The section was successfully processed, and the section
|
|
contents were returned in Buffer.
|
|
@retval EFI_PROTOCOL_ERROR A GUID-defined section was encountered in
|
|
the file with its EFI_GUIDED_SECTION_PROCESSING_REQUIRED
|
|
bit set, but there was no corresponding GUIDed
|
|
Section Extraction Protocol in the handle database.
|
|
*Buffer is unmodified.
|
|
@retval EFI_NOT_FOUND The requested section does not exist.*Buffer is
|
|
unmodified.
|
|
@retval EFI_OUT_OF_RESOURCES The system has insufficient resources to process
|
|
the request.
|
|
@retval EFI_INVALID_PARAMETER The SectionStreamHandle does not exist.
|
|
@retval EFI_WARN_TOO_SMALL The size of the input buffer is insufficient to
|
|
contain the requested section. The input buffer
|
|
is filled and contents are section contents are
|
|
truncated.
