#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);
