LOCON(3)		MBK LOGICAL STRUCTURE DEFINITIONS		LOCON(3)

NAME
     locon - mbk logical connector

DESCRIPTION
     The locon is used to describe a connector of the logical view     of a fig-
     ure. Connectors are describing the cell interface, and are the link between
     its physical and logical views, so the names must be the same.

     The  declarations	needed to work on locon are available in the header file
     "/labo/include/mlo404.h", where '404' is the actual mbk version.

     The following C structure supports the description of the logical connector
     :
	    typedef struct locon {
	       struct locon	*NEXT;
	       char		*NAME;
	       struct losig	*SIG;
	       void		*ROOT;
	       char		DIRECTION;
	       char		TYPE;
	       struct ptype	*USER;
	    } locon_list;

     NEXT		 Pointer to the next locon of the list.

     NAME		 Name of the connector. It identifies the connector,  so
			 it  should  unique in a given logical figure. A logical
			 connector with a given name correspond to the	physical
			 connector or connectors of this name.

     SIG		 Pointer  to  the  signal  linked to the connector. This
			 signal is, of course, unique. See losig(3) for details.

     ROOT		 Pointer to the object it belongs to. This object may be
			 either a lofig, or a loins, depending on  the	type  of
			 the connector.  See lofig(3) and loins for details.

     DIRECTION		 This indicates the way of the information going through
			 the connector.  Six directions are legal :

			 IN		     input

			 OUT		     output

			 INOUT		     input and output

			 UNKNOWN	     no information is available

			 TRISTATE	     tristate output

			 TRANSCV	     tristate output and input

     TYPE		 Character  indicating	if  the  connector  belongs to a
			 model or an instance. It can take two values :

			 EXTERNAL	     for figure connectors

			 INTERNAL	     for instance connectors

			 The TYPE is  needed  to  appropriately  cast  the  ROOT
			 field, and must be approriatly filled by the parsers. A
			 misuse of it may cause strange behaviours.

     USER		 Pointer to a ptype list, see ptype for details, that is
			 a  general purpose pointer used to share information on
			 the connector.
