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();
}
