SYNOPSYS

#include "mut.h"
int delhtitem(table, key)
ht ∗table;
void ∗key;

PARAMETERS

table
Hash table pointer
key
Key used by the hash coding function indicating the item to be deleted

DESCRIPTION

delhtitem() removes an item in the hash table pointed to by table.

RETURN VALUE

If the key doesn't exist, the function returns EMPTYHT, if it does, then its associated value is returned.

EXAMPLE

#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);
}
