DELPTYPE(3)		     MBK UTILITY FUNCTIONS		   DELPTYPE(3)

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);
       }
