NAME
locon - mbk logical connector
DESCRIPTION
The locon is used to describe a connector of the logical view of a figure. Connectors
are describing the cell interface, and are the link between its physical and logical
views, so the names must be the same.
The declarations needed to work on locon are available in the header file
"/labo/include/mlo404.h", where '404' is the actual mbk version.
The following C structure supports the description of the logical connector :
typedef struct locon {
struct locon ∗NEXT;
char ∗NAME;
struct losig ∗SIG;
void ∗ROOT;
char DIRECTION;
char TYPE;
struct ptype ∗USER;
} locon_list;
NEXT Pointer to the next locon of the list.
NAME Name of the connector. It identifies the connector, so it should
unique in a given logical figure. A logical connector with a given
name correspond to the physical connector or connectors of this name.
SIG Pointer to the signal linked to the connector. This signal is, of
course, unique. See losig(3) for details.
ROOT Pointer to the object it belongs to. This object may be either a
lofig, or a loins, depending on the type of the connector. See
lofig(3) and loins for details.
DIRECTION This indicates the way of the information going through the connector.
Six directions are legal :
IN input
OUT output
INOUT input and output
UNKNOWN no information is available
TRISTATE tristate output
TRANSCV tristate output and input
TYPE Character indicating if the connector belongs to a model or an
instance. It can take two values :
EXTERNAL for figure connectors
INTERNAL for instance connectors
The TYPE is needed to appropriatly cast the ROOT field, and must be
approriatly filled by the parsers. A misuse of it may cause strange
behaviours.
USER Pointer to a ptype list, see ptype for details, that is a general
purpose pointer used to share informations on the connector.
