-/**
- The ExtractSection() function processes the input section and
- allocates a buffer from the pool in which it returns the section
- contents. If the section being extracted contains
- authentication information (the section's
- GuidedSectionHeader.Attributes field has the
- EFI_GUIDED_SECTION_AUTH_STATUS_VALID bit set), the values
- returned in AuthenticationStatus must reflect the results of
- the authentication operation. Depending on the algorithm and
- size of the encapsulated data, the time that is required to do
- a full authentication may be prohibitively long for some
- classes of systems. To indicate this, use
- EFI_SECURITY_POLICY_PROTOCOL_GUID, which may be published by
- the security policy driver (see the Platform Initialization
- Driver Execution Environment Core Interface Specification for
- more details and the GUID definition). If the
- EFI_SECURITY_POLICY_PROTOCOL_GUID exists in the handle
- database, then, if possible, full authentication should be
- skipped and the section contents simply returned in the
- OutputBuffer. In this case, the
- EFI_AUTH_STATUS_PLATFORM_OVERRIDE bit AuthenticationStatus
- must be set on return. ExtractSection() is callable only from
- TPL_NOTIFY and below. Behavior of ExtractSection() at any
- EFI_TPL above TPL_NOTIFY is undefined. Type EFI_TPL is
- defined in RaiseTPL() in the UEFI 2.0 specification.
-
-
- @param This Indicates the
- EFI_GUIDED_SECTION_EXTRACTION_PROTOCOL instance.
-
- @param InputSection Buffer containing the input GUIDed section
- to be processed. OutputBuffer OutputBuffer
- is allocated from boot services pool
- memory and contains the new section
- stream. The caller is responsible for
- freeing this buffer.
-
- @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_VAL
- bit as clear, AuthenticationStatus
- must return zero. Both local bits
- (19:16) and aggregate bits (3:0)
- in AuthenticationStatus are
- returned by ExtractSection().
- These bits reflect the status of
- the extraction operation. The bit
- pattern in both regions must be
- the same, as the local and
- aggregate authentication statuses
- have equivalent meaning at this
- level. 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

- not match this instance of the
