SYNOPSYS

       #include "mut.h"
       void delht(table)
       ht *table;

PARAMETER

       table		   Hash table pointer

DESCRIPTION

       delht() removes the hash table pointed to by table from memory.

EXAMPLE

       #include "mut.h"
       checksigname(p)
       lofig_list *p;
       {
       ht *h;
       int i;
       char *amatla;
	  for (i = 0, ptsig = p->LOSIG; ptsig; i++, ptsig = ptsig->NEXT);
	  h = addht(i);
	  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);
		if (!sethtitem(h, amatla, 0)) {
		   printf("N %s;
", amatla);
		}
	     }
	  }
	  delht(h);
       }

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

NAME

       sethtitem - test and set an item in an 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.

SYNOPSYS

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

PARAMETERS

       table		   Hash table pointer

       key		   Key used by the hash coding function to set an item

DESCRIPTION

       sethtitem() adds an item in the hash table pointed to by table, whether it existed or not, and returns an appropriate value.  This is  kind
       of a test and set operator.

RETURN VALUE

       If the key exists, the funtion return 1, if it doesn't, the item is stored and the function returns 0.

EXAMPLE

       #include <stdio.h>
       #include "mut.h"
       checksigname(p)
       lofig_list *p;
       {
       int i;
       losig_list *ptsig;
       locon_list *ptcon;
       ht *h;
       char *amatla;
	  for (i = 0, ptsig = p->LOSIG; ptsig; i++, ptsig = ptsig->NEXT);
	  h = addht(i << 1); /* half empty hash tables are faster! */
	  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);
		if (!sethtitem(h, amatla, 0))
		   printf("node %s is now unique
", amatla);
	     }
	  }
	  delht(h);
       }

ERRORS

       "*** mbk error *** sethtitem 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.
