NAME

       set_menu_mark,  menu_mark  -  get  and  set  the menu mark
       string


SYNOPSIS

       #include <menu.h>
       int set_menu_mark(MENU *menu, const char *mark);
       const char *menu_mark(const MENU *menu);


DESCRIPTION

       In order to make menu selections visible on  older  termi-
       nals  without  highlighting  or color capability, the menu
       library marks selected items  in  a  menu  with  a  prefix
       string.

       The  function  set_menu_mark  sets the mark string for the
       given menu.  Calling set_menu_mark with a null  menu  item
       will  abolish  the  mark  string.   Note that changing the
       length of the mark string for a menu  while  the  menu  is
       posted is likely to produce unhelpful behavior.

       The  default string is "-" (a dash). Calling set_menu_mark
       with a non-NULL menu argument will change this default.

       The function menu_mark returns the menu's mark string  (or
       NULL if there is none).


RETURN VALUE

       The  function  menu_mark  returns  a pointer (which may be
       NULL).  It does not set errno.

       The function set_menu_mark may return the following  error
       codes:

       E_OK The routine succeeded.

       E_BAD_ARGUMENT
            Routine  detected  an incorrect or out-of-range argu-
            ment.

       E_SYSTEM_ERROR
            System error occurred (see errno).

NOTES

       The header file <menu.h> automatically includes the header
       file <curses.h>.


PORTABILITY

       These  routines  emulate  the System V menu library.  They
       were not supported on Version 7 or BSD versions.
