8/7/86 forum_check_meetings, fckm Syntax: fckm {meeting_names} {-control_args} Function: establishes a list of changed meetings which can then be successively visited by the next_meeting (nm) request within the forum subsystem. Arguments: meeting_names are names of meetings to be checked. The star convention is allowed. If meeting_names are given, the list of changed meetings will consist of any changed meetings in the list given. If no meeting_names are given, then the list consists of all changed meetings which may be found in the "forum" search list. Control arguments: -exclude meeting_names, -ex meeting_names excludes the meetings identified by meeting_names from the changed meeting list. -from DT, -fm DT selects meetings which have changed since the specified time. DT is any string acceptable to the convert_date_to_binary_ subroutine. The default is the current time. -list, -ls prints the name of each changed meeting and the number of new transactions in each. Notes: The list of changed meetings is accessible to applications outside of the forum subsystem. The external variable forum_data_$meeting_list points to the following structure, which is defined in the include file forum_meeting_list.incl.pl1: dcl 1 forums_array aligned, 2 version char (8), 2 no_selected fixed bin, 2 no_changed fixed bin, 2 forums (0 refer (forums_array.no_selected)), 3 long_name char (26) unaligned, 3 short_name char (26) unaligned, 3 path_name char (168) unaligned, 3 chairman char (32) unaligned, 3 uid bit (36) aligned, 3 count fixed bin, 3 last_seen fixed bin, 3 last_trans fixed bin, 3 flags unaligned, 4 eligible bit (1), 4 removed bit (1), 4 notify bit (1), 4 attending bit (1), 4 two_names bit (1), 4 read_only bit (1), 4 attended bit (1), 4 adjourned bit (1), 4 processed bit (1), 4 mbz bit (27), 3 order fixed bin; where version is set to forum_meeting_list_version_1. no_selected is the number of meetings in the array. no_changed is the number of changed meetings in the list. long_name is the primary name of the meeting. short_name is an additional name of the meeting. Valid only if the two_names flag is set. path_name is the full pathname of the meeting. chairman is the user_id, as User.Project, of the meeting's chairman. uid is the storage system unique identifier of the meeting. count is the number of new transactions in the meeting. last_seen is the index of the most recent transaction that this user has seen in this meeting. last_trans is the index of the last transaction in the meeting. eligible is set if the user is eligible to attend the meeting. removed is set if the user or chairman has turned off the participating switch for this meeting. notify is set if the user's notify switch is on for this meeting. attending is set if the user was attending the meeting when the command was executed. two_names is set when the short_name field is valid. read_only is set if the user does not have access to enter transactions in the meeting. attended is set if the user has ever attended the meeting. adjourned is set if the meeting is adjourned. processed is set if the next_meeting command has already visited this meeting. See "Notes on structure" below. mbz is always set to ""b. order is an array which orders the meetings alphabetically. See "Notes on structure" below. Notes on structure: The array contains information about 'no_selected' meetings. The 'order' array contains sorting information (alphabetical order by short name) that can be used in the following way: do idx = 1 to forums_array.no_selected; process (forums_array.forums (forums_array.forums(idx).order)); end; where process is the name of a procedure that uses the information about a single meeting. This procedure should set the 'processed' flag to indicate that this entry has been used. The forum 'next_meeting' request obeys this protocol. ----------------------------------------------------------- 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. . ----------------------------------------------------------- Permission to use, copy, modify, and distribute these programs and their documentation for any purpose and without fee is hereby granted,provided that the below copyright notice and historical background appear in all copies and that both the copyright notice and historical background and this permission notice appear in supporting documentation, and that the names of MIT, HIS, BULL or BULL HN not be used in advertising or publicity pertaining to distribution of the programs without specific prior written permission.
