+ Retrieves handlers of type EXTRACT_GUIDED_SECTION_GET_INFO_HANDLER and

+ @param[in] SectionGuid A pointer to the GUID associated with the handlersof the GUIDed
+ section type being retrieved.
+ @param[out] GetInfoHandler Pointer to a function that examines a GUIDed section and returns
+ the size of the decoded buffer and the size of an optional scratch
+ buffer required to actually decode the data in a GUIDed section.
+ This is an optional parameter that may be NULL. If it is NULL, then
+ the previously registered handler is not returned.
+ @param[out] DecodeHandler Pointer to a function that decodes a GUIDed section into a caller
+ allocated output buffer. This is an optional parameter that may be NULL.
+ If it is NULL, then the previously registered handler is not returned.
+
+ @retval RETURN_SUCCESS The handlers were retrieved.
+ @retval RETURN_NOT_FOUND No handlers have been registered with the specified GUID.
