NAME

       delptype - delete an element of a ptype_list

SYNOPSYS

       #include "mut.h"
       ptype_list ∗delptype(pthead, type)
       ptype_list ∗pthead;
       long type;

PARAMETERS

       pthead              Pointer to a ptype list

       type                The pointer of this type is to be deleted.

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 maintained, 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);
       }
