28       #include "mut.h"
29       check(p)
30       losig_list *p;

32       char *amatla;
33       losig_list *ptsig;
34       locon_list *ptcon;
35       ht *h;
36          for (i = 0, ptsig = p->LOSIG; ptsig; i++, ptsig = ptsig->NEXT);
37          h = addht(i);
38          /* two connectors can't have the same name! */
39          for (ptcon = p->LOCON; ptcon; ptcon = ptcon->NEXT)
40             addhtitem(h, ptcon->NAME, 0);
41          for (ptsig = p->LOSIG; ptsig; ptsig = ptsig->NEXT) {
42             if (ptsig->TYPE == INTERNAL) {
43                amatla = getsigname(ptsig);
44                /* this is nicely done with sethtitem! */
45                if (gethtitem(h, amatla) == EMPTYHT) {
46                   printf("N %s;\n", amatla);
47                   addhtitem(h, amatla, 0);
