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);
