NAME
       addchain - create a chain and add it to a list

       Paris, France.

SYNOPSYS
       #include "mut.h"
       chain_list *addchain(pthead, ptdata)
       chain_list *pthead;
       void *ptdata;

PARAMETERS
       pthead		   Pointer to a chain_list

       ptdata		   Generic pointer to any kind of information

DESCRIPTION
       addchain creates a new chain element and adds it to the front of the list pointed to by pthead, and becomes itself the list head.
       The chain_lists are mosty used to create temporary lists of homogeneous elements, for binary trees, and so on.
       The ptdata points to any kind of list or may itself be a value, if proper cast is performed at compilation time, and fills the  DATA  field
       of the chain structure.	For details on the structure, see chain(3).

RETURN VALUE
       addchain returns a pointer to the new head of list.

EXAMPLE
       #include "mut.h"
       #include "mlo.h"
       chain_list *get_external_connectors(ptfig)
       lofig_list *ptfig;
       {
       locon_list *pt = ptfig->LOCON;
       chain_list *c = NULL; /* initialized for regularity */
	  while (pt) {
	     if (pt->TYPE == EXTERNAL)
		c = addchain(c, (void *)pt)
	     pt = pt->NEXT;
	  }
	  return c;
       }
