   error_table_$no_append
      insufficient access to add a message to the recipient's mailbox.
   error_table_$wakeup_denied
      insufficient access to send the message interactively; the

   error_table_$no_info
      access class restrictions prevent the sender from finding out
      whether the message was sent.


Notes:  The pathname of the mailbox sent to is
>udd>Project_id>Person_id>Person_id.mbx.



:Entry:  acknowledge:  02/06/84 send_message_$acknowledge


Function:  This entry point sends a message to be acknowledged when
read by the recipient.


Syntax:
declare send_message_$acknowledge entry (char(*), char(*), char(*),
     fixed bin(35));
call send_message_$acknowledge (person, project, message, code);


Arguments:
person
   is the registered Person_id of the recipient.  (Input)
project
   is a Project_id on which the recipient is registered.  (Input)
message
   is the text of the message to be sent.  (Input)
code
   is a standard status code.  (Output)


Notes: The acknowledgement is an interactive message of the form
"Acknowledged" if the message is printed immediately by the recipient,
or "Acknowledge message of <time>" if printed later.


:Entry:  express:  02/06/84 send_message_$express


Function: sends a message only if the recipient is logged in and
accepting interactive messages by means of the accept_messages
command.  If the message cannot be sent interactively, it is not added
to the recipient's mailbox.


Syntax:
declare send_message_$express entry (char(*), char(*), char(*),
     fixed bin(35));
call send_message_$express (person, project, message, code);


Arguments:
person
   is the registered Person_id of the recipient.  (Input)
project
   is a Project_id on which the recipient is registered.  (Input)
message
   is the text of the message to be sent.  (Input)
code
   is a standard status code.  (Output)


:Entry:  notify_mail:  02/06/84 send_message_$notify_mail

Historical Background

This edition of the Multics software materials and documentation is provided and donated
to Massachusetts Institute of Technology by Group BULL including BULL HN Information Systems Inc. 
as a contribution to computer science knowledge.  
This donation is made also to give evidence of the common contributions of Massachusetts Institute of Technology,
Bell Laboratories, General Electric, Honeywell Information Systems Inc., Honeywell BULL Inc., Groupe BULL
and BULL HN Information Systems Inc. to the development of this operating system. 
Multics development was initiated by Massachusetts Institute of Technology Project MAC (1963-1970),
renamed the MIT Laboratory for Computer Science and Artificial Intelligence in the mid 1970s, under the leadership
of Professor Fernando Jose Corbato. Users consider that Multics provided the best software architecture 
for managing computer hardware properly and for executing programs. Many subsequent operating systems 
incorporated Multics principles.
Multics was distributed in 1975 to 2000 by Group Bull in Europe , and in the U.S. by Bull HN Information Systems Inc., 
as successor in interest by change in name only to Honeywell Bull Inc. and Honeywell Information Systems Inc. .
