set_item_userptr(3menu) [debian man page]

menu_userptr(3MENU)													       menu_userptr(3MENU)

NAME

       mitem_userptr - associate application data with a menu item

SYNOPSIS

       #include <menu.h>
       int set_item_userptr(ITEM *item, void *userptr);
       void *item_userptr(const ITEM *item);

DESCRIPTION

       Every  menu  item  has  a  field that can be used to hold application-specific data (that is, the menu-driver code leaves it alone).  These
       functions get and set that field.

RETURN VALUE

       The function item_userptr returns a pointer (possibly NULL).  It does not set errno.

       The set_item_userptr always returns E_OK (success).

SEE ALSO

       ncurses(3NCURSES), 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.

       The user pointer is a void pointer.  We chose not to leave it as a char pointer for SVr4 compatibility.

NAME

       menu_value - set and get menu item values

SYNOPSIS

       #include <menu.h>
       int set_item_value(ITEM *item, bool value);
       bool item_value(const ITEM *item);

DESCRIPTION

       If  you	turn  off  the menu option O_ONEVALUE (e.g., with set_menu_opts or menu_opts_off; see opts(3MENU)), the menu becomes multi-valued;
       that is, more than one item may simultaneously be selected.

       In a multi_valued menu, you can used set_item_value to select the given menu item (second argument TRUE) or deselect  it  (second  argument
       FALSE).

RETURN VALUE

       The function set_item_value returns one of the following:

       E_OK The routine succeeded.

       E_SYSTEM_ERROR
	    System error occurred (see errno).

       E_REQUEST_DENIED
	    The menu driver could not process the request.
