/**
The ExtractSection() function processes the input section and
returns a pointer to the section contents. If the section being
extracted does not require processing (if the section
GuidedSectionHeader.Attributes has the
EFI_GUIDED_SECTION_PROCESSING_REQUIRED field cleared), then
OutputBuffer is just updated to point to the start of the
section's contents. Otherwise, *Buffer must be allocated
from PEI permanent memory.
@param This Indicates the
EFI_PEI_GUIDED_SECTION_EXTRACTION_PPI instance.
Buffer containing the input GUIDed section to be
processed. OutputBuffer OutputBuffer is
allocated from PEI permanent memory and contains
the new section stream.
@param InputSection A pointer to the input buffer, which contains
the input section to be processed.
@param OutputBuffer A pointer to a caller-allocated buffer, whose
size is specified by the contents of OutputSize.
@param OutputSize A pointer to a caller-allocated
UINTN in which the size of *OutputBuffer
allocation is stored. If the function
returns anything other than EFI_SUCCESS,
the value of OutputSize is undefined.
@param AuthenticationStatus A pointer to a caller-allocated
UINT32 that indicates the
authentication status of the
output buffer. If the input
section's GuidedSectionHeader.
Attributes field has the
EFI_GUIDED_SECTION_AUTH_STATUS_VALID
bit as clear,
AuthenticationStatus must return
zero. These bits reflect the
status of the extraction
operation. If the function
returns anything other than
EFI_SUCCESS, the value of
AuthenticationStatus is
undefined.
@retval EFI_SUCCESS The InputSection was
successfully processed and the
section contents were returned.
@retval EFI_OUT_OF_RESOURCES The system has insufficient
resources to process the request.
@retval EFI_INVALID_PARAMETER The GUID in InputSection does
not match this instance of the
GUIDed Section Extraction PPI.
