NAME

       gethtitem - searches an item in a hash table

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();
       }
