PHREF(3)						MBK PHYSICAL STRUCTURE DEFINITIONS						  PHREF(3)

NAME

       phref - mbk physical reference

DESCRIPTION

       The  phref structure is used to describe a reference belonging to a symbolic layout model, see phfig(3) for details.  A reference allows to
       name a point anywhere in a given model. It may then be seen as a name, and not anymore as a couple of coordinates.  References  are  mostly
       used for cell programming and multi-access connector representation.

       The declarations needed to work on phref are available in the header file "/labo/include/mph402.h", where '402' is the actual mbk version.

       The following C structure supports the description of the reference :
	      typedef struct phref {
		 struct phref	  *NEXT;
		 char		  *FIGNAME;
		 char		  *NAME;
		 long		  XREF,YREF;
		 struct ptype	  *USER;
	      } phref_list;

       NEXT		   Pointer to the next reference in the list.

       FIGNAME		   Kind of reference. Gives information about the possible uses of the object.	Some FIGNAME are in use today :

			   "ref_con"	       for multi-access connectors

			   "ref_ref"	       for all other uses

       NAME		   Name of the reference. The refence is identified by its name, so it should be unique at a given hierarchical level.

       XREF, YREF	   Coordinates of the point beeing referenced.

       USER		   Pointer  to a ptype list, see ptype(3) for details, that is a general purpose pointer used to share informations on the
			   reference.
