NAME

       addphins - create a physical instance

SYNOPSYS

       #include "mph.h"
       phins_list ∗addphins(ptfig, figname, insname, sym, x, y)
       phfig_list ∗ptfig;
       char ∗figname;
       char ∗insname;
       char sym;
       long x, y;

PARAMETERS

       ptfig               Pointer to the figure in which the instance should be added

       figname             Instance model name

       insname             Instance name

       sym                 Geometrical operation performed on the instance

       x, y                Coordinates of the lower left corner of the instance

DESCRIPTION

       addphins  creates  a new instance whose lower left corner is at the given coordinates, and adds it to the
       list of instances pointed to by ptfig->PHINS. The new instance is added in front of the list, and becomes
       itself the list head.
       The parameters figname, insname, sym, x and y fill respectivly the FIGNAME,  INSNAME,  TRANSF,  XINS  and
       YINS fields of the phins structure.
       The  addphins function does not check in memory or on disk to see if the instanciated model exists, since
       no informations on it are needed.
       The coordinates are not transformation dependant. It means that the transformation  is  performed  before
       placing the instance at the given point.  For details on the structure, see phins(3).

RETURN VALUE

       addphins returns a pointer to the newly created instance.

ERRORS

       "∗∗∗ mbk error ∗∗∗ addphins figure figname cannot be part of itself"
              The  instance  has  for model name of the figure on the which it is to be added.  It's illegal and
              dangerous. This check is made at the actual hierachy level only, not recursivly on the  structure,
              so it still may happend.

       "∗∗∗ mbk error ∗∗∗ illegal addphins transformation sym in : insname"
              The geometrical operation is not in the legal range. See phins(3) for a complete list of values.

       "∗∗∗ mbk error ∗∗∗ illegal addphins duplicate instance name : insname"
              The instance name is an identifier, so it can't appear twice in the same figure.

EXAMPLE

       #include "mph.h"
       phins_list ∗ins_dup(pfd, pfs) /∗ duplicate instances ∗/
       phfig_list ∗pfd, ∗pfs;
       {
       phins_list ∗pi;
          for (pi = pfs->phins; pi != NULL; pi = pi->NEXT)
             addphins(pfd, pi->FIGNAME, pi->INSNAME, pi->TRANSF,
                                pi->XINS, pi->YINS);
          return pfd->PHINS;
       }
