NAME

       delchain - delete an element of a chain_list

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 "mut.h"
       chain_list *delchain(pthead, ptdel)
       chain_list *pthead;
       chain_list *ptdel;

PARAMETERS

       pthead		   Pointer to a chain list

       ptdel		   Pointer to the element to be deleted.

DESCRIPTION

       delchain deletes the element of the chain_list pointed to by ptdel in the list pointed to by pthead.  The list consistency is  maintainded,
       and the element put back in the list of free blocks.

RETURN VALUE

       delchain  returns  a  pointer  to  the  new head of list if the ptdel pointer used to belong to the list. In most case, it has the value of
       pthead. If the pointer doesn't belong to the list, NULL is returned.

ERROR

       "*** mbk error *** delchain impossible : pointer NULL"
	      At least one of the arguments are pointing to NULL, and that clear that such a pointer can't be deleted, or used for freeing.

EXAMPLE

       #include "mut.h"
       void delete_match(c0, c1)
       chain_list *c0, *c1;
       {
       chain_list *t0, *t1, *next;
	  for (t0 = c0; t0; t0 = next)
	     for (t1 = c1; t1; t1 = t1->NEXT)
		if (t1->DATA == t0->DATA)
		   next = delchain(c0, t0);
       }

NAME

       addptype - create a ptype and add it to a ptype_list

SYNOPSYS

       #include "mut.h"
       ptype_list *addptype(pthead,type,ptdata)
       ptype_list *pthead;
       void *ptdata;
       long type;

PARAMETERS

       pthead		   Pointer to a ptype list

       type		   Flag indicating the pointer owner

       ptdata		   Generic pointer to any kind of information

DESCRIPTION

       addptype creates a new ptype element and adds it to the front of the list pointed to by pthead, and becomes itself the list head.
       The ptype_lists are mosty used to create lists of homogeneous elements in mbk, but also for trees, graphs, and so on.
       The type argument indicates the pointer type, at the C type meaning, for its owner.
       The types allow to access the pointers with adequat cast, and for example to share informations in the USER fields of mbk structures.
       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 ptype structure.	For details on the structure, see ptype(3).

RETURN VALUE

       addptype returns a pointer to the new head of list.

EXAMPLE

       #include "mut.h"
       #include "mph.h"
       void corner(ptfig, name)
       phfig_list *ptfig;
       char *name;
       {
       phins_list *i = getphins(ptfig, name);
       num_list *ptnum;
       phfig_list *model;
	  model = getphfig(i->FIGNAME);
	  ptnum = addnum((num_list *)NULL, model->X2 - model->X1);
	  ptnum = addnum(ptnum, model->Y2 - model->Y1);
	  i->USER = addptype(i->USER, (long)PLACEABOX, (void *)ptnum);
       }
