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