DESCRIPTION

       delptype deletes the element of the ptype_list that has the type type in the list pointed to by pthead.	 The  list  consistency  is  main-
       tained, and the element put back in the list of free blocks.

RETURN VALUE

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

ERROR

       "*** mbk error *** delptype impossible : pthead = NULL"
	      The pointer to the head of list is NULL, and that clear that such a list can't be ran thru.

EXAMPLE

       #include "mut.h"
       #include "mph.h"
       void delete_user(ptfig)
       phfig_list *ptfig;
       {
       phins_list *i;
	  for (i = ptfig->PHINS; i; i = i->NEXT)
	     i->USER = delptype(i->USER, PLACEABOX);
