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.
