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.
