the PEI Foundation or the EFI_PEI_FILE_LOADER_PPI instance
|
|
calls the appropriate instance of the GUIDed Section Extraction PPI

to extract the section stream contained therein.

Processes the input section and returns the data contained therein

along with the authentication status.
|
|
|
|
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.
|
|
@param InputSection Buffer containing the input GUIDed section to be
|
|
processed.
|
|
@param OutputBuffer *OutputBuffer is allocated from PEI permanent memory
|
|
and contains the new section stream.
|
|
@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.
