Retrieves handlers of type EXTRACT_GUIDED_SECTION_GET_INFO_HANDLER and
EXTRACT_GUIDED_SECTION_DECODE_HANDLER for a specific GUID section type.
Retrieves the handlers associated with SectionGuid and returns them in
GetInfoHandler and DecodeHandler.
If the GUID value specified by SectionGuid has not been registered, then
return RETURN_NOT_FOUND.
If SectionGuid is NULL, then ASSERT().
@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.
