MirOS Manual: menu_mark(3), set_menu_mark(3)


menu_mark(3)        UNIX Programmer's Manual         menu_mark(3)

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 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 NULL on error.  The function
     set_menu_mark 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.

SEE ALSO

     curses(3), menu(3).

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.
