menu_mark3
Get and set the menu mark string
Usage
#include <menu.h>
int set_menu_mark(MENU *menu, const char *mark); const char *menu_mark(const MENU *menu);
Overview
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:
|
The routine succeeded. |
|---|---|
|
Routine detected an incorrect or out-of-range argument. |
|
System error occurred (see errno(3)). |
Portability
These routines emulate the System V menu library. They were not supported on Version 7 or BSD versions.
