READUPDATELOCK[X}
Locks, then reads the record from the current position in the file in the same manner as
the combination of LOCKREC and READUPDATE[X]. This procedure operates only
on Guardian objects.
RECEIVEINFO
(superseded by FILE_GETRECEIVEINFO_) Obtains the four-word process ID,
message tag, error recovery (sync ID), and request-related (file number, read count, and
I/O type) information associated with the last message read from the $RECEIVE file.
This procedure does not have a C syntax, because it is superseded and should not be
used for new development. This procedure is supported only for compatibility with
previous software.
_status_lt (<returned_value>) An error occurred (call FILEINFO).
_status_eq (<returned_value>) The READUPDATE[X] is successful.
_status_gt (<returned_value>) A system message is received through
$RECEIVE.
