+ 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 Pointer to the PEI Services Table.
+ @param This Indicates the calling context
+ @param SectionType 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
+ 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 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.
