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();
