There may be multiple different GUIDs associated with the GUIDed 23 section extraction protocol. That is, all instances of the GUIDed section 24 extraction protocol must have the same interface structure. 25 26 --*/ 27 28 #ifndef _GUIDED_SECTION_EXTRACTION_PROTOCOL_H 29 #define _GUIDED_SECTION_EXTRACTION_PROTOCOL_H 30 31 #include "EfiFirmwareFileSystem.h" 32 33 // 34 // Protocol GUID definition.
