NAME
       addlosig - create a logical signal

ORIGIN
       This  software  belongs	to  the  ALLIANCE CAD SYSTEM developed by the ASIM team at LIP6 laboratory of Universite Pierre et Marie CURIE, in
       Paris, France.

SYNOPSYS
       #include "mlo.h"
       losig_list *addlosig(ptfig, index, namechain, type)
       lofig_list *ptfig;
       long index;
       chain_list *namechain;
       char type;

PARAMETERS
       ptfig		   Pointer to the figure in which the signal should be added

       index		   Signal index

       namechain	   List of names of the signal

       type		   Signal type

DESCRIPTION
       addlosig creates a new signal, and adds it to the list of signals pointed to by ptfig->LOSIG. The new signal is added in front of the list,
       and becomes itself the list head.
       The type parameter can take two values :

	      EXTERNAL		  The signal is attached to at least one connector of the figure.

	      INTERNAL		  The signal is only attached to instance or transistor connector.
       The  index and type arguments fill the INDEX and TYPE fields of the losig(3) structure. The index is the signal identifier, so it should be
       unique at a given hierarchical level.
       The namechain argument is a list of names, given in a chain_list.  See chain(3) for details.

RETURN VALUE
       addlosig returns a pointer to the newly created signal.

ERRORS
       "*** mbk error *** addlosig impossible signal index already exist in figure ptfig->NAME"
	      The index is already used in an other signal, and since it's the signal identifier, it can't be.

EXAMPLE
       #include "mlo.h"
       losig_list *merge_and_create(pt, s0, s1) /* merge two signal in a third */
       lofig_list *pt;
       losig_list *s0, *s1;
       {
       chain_list *c;
       losig_list *s;
       long max_index;
	  /* merge names */
	  for (c = s0->NAMECHAIN; c; c = c->NEXT)
	     s1->NAMECHAIN = addchain(s1->NAMECHAIN, c);
	  /* find maximum index */
	  for (s = pt->LOSIG; s; s = s->NEXT)
	     if (max_index < s->INDEX)
		max_index = s->INDEX;
	  s = addlosig(pt, ++max_index, s1->NAMECHAIN,
		s0->TYPE == EXTERNAL || s1->TYPE == EXTERNAL ?
		EXTERNAL : INTERNAL);
	  dellosig(pt, s0);
	  dellosig(pt, s1);
	  return s;
       }
