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);
       }
