02/03/84  object_info_

The object_info_ subroutine returns structural and identifying
information extracted from an object segment.  It has three entry
points returning progressively larger amounts of information.


Entry points in object_info_:
   (List is generated by the help command)


:Entry:  brief:  02/03/84 object_info_$brief


Function:  This entry point returns only the structural information
necessary to locate the object's major sections.


Syntax:
declare object_info_$brief entry (ptr, fixed bin(24), ptr,
     fixed bin(35));
call object_info_$brief (seg_ptr, bc, info_ptr, code);


Arguments:
seg_ptr
   is a pointer to the base of the object segment.  (Input)
bc
   is the bit count of the object segment.  (Input)
info_ptr
   is a pointer to the object_info structure in which the object
   information is returned.  It is defined in the include file
   object_info.incl.pl1.  (Input)
code
   is a standard status code.  (Output)


:Entry:  display:  02/03/84 object_info_$display


Function:  This entry point returns, in addition to the information
returned in the object_info_$brief entry point, all the identifying
data required by certain object display commands, such as the
print_link_info command.


Syntax:
declare object_info_$display entry (ptr, fixed bin(24), ptr,
     fixed bin(35));
call object_info_$display (seg_ptr, bc, info_ptr, code);


Arguments:
seg_ptr
   is a pointer to the base of the object segment.  (Input)
bc
   is the bit count of the object segment.  (Input)
info_ptr
   is a pointer to the object_info structure in which the object
   information is returned.  It is defined in the include file
   object_info.incl.pl1.  (Input)
code
   is a standard status code.  (Output)


:Entry:  long:  02/03/84 object_info_$long


Function:  This entry point returns, in addition to the information
supplied by the object_info_$display entry point, the data required by
the Multics binder.


Syntax:
declare object_info_$long entry (ptr, fixed bin(24), ptr,
     fixed bin(35));
call object_info_$long (seg_ptr, bc, info_ptr, code);


Arguments:
seg_ptr
   is a pointer to the base of the object segment.  (Input)
bc
   is the bit count of the object segment.  (Input)
info_ptr
   is a pointer to the object_info structure in which the object
   information is returned.  It is defined in the include file
   object_info.incl.pl1.  (Input)
code
   is a standard status code.  (Output)

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. .
