ht ∗table;
void ∗key;
```

## PARAMETERS

- *table*

  Hash table pointer

- *key*

  Key used by the hash coding function indicating the item to be deleted

## DESCRIPTION

## RETURN VALUE

```
#include "mut.h"
checksigname(p, h)
lofig_list ∗p;
ht ∗h;
{
int i;
char ∗amatla;
	/∗ check for signal and connector name unicity ∗/
	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;\n", amatla);
			}
		}
	}
	/∗ keep only internal signal names in the hash table ∗/
	for (ptcon = p->LOCON; ptcon; ptcon = ptcon->NEXT)
		(void)delhtitem(h, ptcon->NAME);
