LOCON(3) MBK LOGICAL STRUCTURE DEFINITIONS LOCON(3) 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 con- nector : 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 de- tails. 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 appropriately cast the ROOT field, and must be approriatly filled by the parsers. A misuse of it may cause strange behav- iours. USER Pointer to a ptype list, see ptype for details, that is a general purpose pointer used to share in- formation on the connector.
