NAME¶
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 terminals 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 argument.
- E_SYSTEM_ERROR
- System error occurred (see errno).
SEE ALSO¶

menu(3MENU).
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.
