NAME¶
menu_userptr - associate application data with a menu item
SYNOPSIS¶
#include <menu.h>
int set_menu_userptr(MENU *menu, void *userptr);
void *menu_userptr(const MENU *menu);
DESCRIPTION¶
Every menu and 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 the menu user pointer field.
RETURN VALUE¶
menu_userptr returns a pointer (which may be
NULL). It does not
set errno.
set_menu_userptr 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.
