       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.

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();
       }
