NAME
     menuhook:    setiteminit,    iteminit,    setitemterm,
     itemterm,    setmenuinit,    menuinit,    setmenuterm,
     menuterm  -  assign   application-specific   routines   for
     automatic invocation by menus

SYNOPSIS
     #include <menu.h>

     int setiteminit(MENU *menu, void (*func)(MENU *));
     void (*)(MENU *) iteminit(MENU *menu);
     int setitemterm(MENU *menu, void (*func)(MENU *));
     void (*)(MENU *) itemterm(MENU *menu);
     int setmenuinit(MENU *menu, void (*func)(MENU *));
     void (*)(MENU *) menuinit(MENU *menu);
     int setmenuterm(MENU *menu, void (*func)(MENU *));
     void (*)(MENU *) menuterm(MENU *menu);

DESCRIPTION
     setiteminit assigns the application-defined function to be
     called  when  the  menu is posted and just after the current
     item changes.  iteminit returns a pointer to the item  ini-
     tialization  routine, if any, called when the menu is posted
     and just after the current item changes.

     setitemterm assigns an application-defined function to  be
     called when the menu is unposted and just before the current
     item changes.  itemterm returns a pointer to  the  termina-
     tion  function, if any, called when the menu is unposted and
     just before the current item changes.

     setmenuinit assigns an application-defined function to  be
     called  when  the  menu is posted and just after the top row
     changes on a posted menu.  menuinit returns  a  pointer  to
     the  menu  initialization  routine,  if any, called when the
     menu is posted and just after  the  top  row  changes  on  a
     posted menu.

     setmenuterm assigns an application-defined function to  be
     called when the menu is unposted and just before the top row
     changes on a posted menu.  menuterm returns  a  pointer  to
     the  menu  termination routine, if any, called when the menu
     is unposted and just before the top row changes on a  posted
     menu.

RETURN VALUE
     Routines that return pointers always return NULL  on  error.
     Routines that return an integer return one of the following:
     E_OK           - The routine returned successfully.
     E_SYSTEM_ERROR - System error.
