ORIGIN¶

This software belongs to the ALLIANCE CAD SYSTEM developed by the ASIM team at LIP6 laboratory of Université 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"
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;\n", amatla);
				addhtitem(h, amatla, 0);
			}
		}
	}
	delht();
}
