DESCRIPTION

9       The phcon structure is used to describe a connector belonging to a sym‐
10       bolic layout model, see phfig(3) for details. A  strong  convention  on
11       the  mbk data structure is that two connector internally wired have the
12       same name, the 'logical' name.
13
14       The declarations needed to work on phcon are available  in  the  header
15       file "/labo/include/mph402.h", where '402' is the actual mbk version.
16
17       The following C structure supports the description of the connector :
18              typedef struct phcon {
19                 struct phcon     ∗NEXT;
20                 char             ∗NAME;
21                 long             INDEX;
22                 long             XCON, YCON;
23                 long             WIDTH;
24                 char             ORIENT;
25                 char             LAYER;
26                 struct ptype     ∗USER;
27              } phcon_list;
28
29       NEXT                Pointer to the next connector of the model.
30
31       NAME                Name  of  the  connector. A model may posseses more
32                           than one connector with a given name, if  they  are
33                           internally wired.
34
35       INDEX               Index of the connector. Since a model may have many
36                           connectors with the same name, it is needed  to  be
37                           able  to point out one of them. The index allows to
38                           distinguish every  connector  using  a  topological
39                           order.  This  field is filled by the addphcon func‐
40                           tion, and shall not be modified otherwise.
41
42       XCON, YCON          Connector coordinates. the point (XCON, YCON)  must
43                           be  placed  on or inside of the abutment box of the
44                           model.
45
46       ORIENT              Caracter indicating the face of the  model  on  the
47                           which  the  connector  is placed.  It may take four
48                           values :
