menu_mark()

NAME

menu_mark(), set_menu_mark() - get and set the menu mark string

SYNOPSIS

#include <menu.h>


int set_menu_mark(MENU *menu, char *mark);
char *menu_mark(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(3) sets the mark string for the given menu. Calling set_menu_mark(3) 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(3) wiith a NULL menu argument will change this default.

The function menu_mark(3) returns the menu's mark string (or NULL if there is none).

RETURN VALUE

The function menu_mark(3) returns NULL on error. The function set_menu_mark(3) may return the following error codes:

E_OK

The routine succeeded.

E_SYSTEM_ERROR

System error occurred (see errno

E_BAD_ARGUMENT

Routine detected an incorrect or out-of-range argument.

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.
