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.
