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.
