NAME

SYNOPSYS

       #include "mut.h"
       int gethtitem(table, key)
       ht *table;
       void *key;

PARAMETERS

       table		   Hash table pointer

       key		   Key used by the hash coding function

DESCRIPTION

       gethtitem() searches an item in the hash table pointed to by table.

RETURN VALUE

       If the key key exists, the associated value is returned, if it doesn't, the function returns EMPTYHT.

EXAMPLE

       #include <stdio.h>
       #include "mut.h"
       check(p)
       losig_list *p;
       {
       char *amatla;
       losig_list *ptsig;
       locon_list *ptcon;
       ht *h;
	  for (i = 0, ptsig = p->LOSIG; ptsig; i++, ptsig = ptsig->NEXT);
	  h = addht(i);
	  /* two connectors can't have the same name! */
	  for (ptcon = p->LOCON; ptcon; ptcon = ptcon->NEXT)
	     addhtitem(h, ptcon->NAME, 0);
	  for (ptsig = p->LOSIG; ptsig; ptsig = ptsig->NEXT) {
	     if (ptsig->TYPE == INTERNAL) {
		amatla = getsigname(ptsig);
		/* this is nicely done with sethtitem! */
		if (gethtitem(h, amatla) == EMPTYHT) {
		   printf("N %s;
", amatla);
		   addhtitem(h, amatla, 0);
		}
	     }
	  }
	  delht();
       }

ADDHTITEM(3)						MBK HASH TABLE MANAGEMENT FUNCTIONS					      ADDHTITEM(3)

NAME

       addhtitem - adds a new item in a hash table.

ORIGIN

       This  software  belongs	to  the  ALLIANCE CAD SYSTEM developed by the ASIM team at LIP6 laboratory of Universite Pierre et Marie CURIE, in
       Paris, France.

       Web : http://asim.lip6.fr/recherche/alliance/
       E-mail : alliance-users@asim.lip6.fr

SYNOPSYS

       #include "mut.h"
       void addhtitem(table, key, value)
       ht *table;
       void *key;
       int value;

PARAMETERS

       table		   Hash table pointer

       key		   Key used by the hash coding function to add the item

       value		   Value associated with the key

DESCRIPTION

       addhtitem() adds a new item in the hash table pointed to by table.  If the key already exists, the old value is changed	to  the  new  one.
       Value  must  be distinct from EMPTYHT and DELETEHT.  The length of the table increases automatically when the length given in addht() leads
       to a performance shut down.

EXAMPLE

       #include "mut.h"
       #include "mlo.h"
       void conHenter(h, ptfig)
       ht *h;
       lofig_list *ptfig;
       {
       locon_list *ptcon;
	  /* since connector names are unique, add them without check */
	  for (ptcon = p->LOCON; ptcon; ptcon = ptcon->NEXT)
	     addhtitem(h, ptcon->NAME, 0);
       }

ERRORS

       "*** mbk error *** addhtitem impossible : value is EMPTYHT or DELETEHT"
	      The values EMPTYHT, -1,  and DELETEHT, -2, are reserved for internal use, sorry.

DIAGNOSTICS

       The value must be distinct from -1 and -2.
