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);
       }
