menu_userptr(3) UNIX Programmer's Manual menu_userptr(3)
menu_userptr - associate application data with a menu item
#include <menu.h>
int set_menu_userptr(MENU *menu, void *userptr);
void *menu_userptr(const MENU *menu);
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.
Except for menu_userptr (which returns NULL on error), each
function returns one of the following:
E_OK The routine succeeded.
E_SYSTEM_ERROR
System error occurred (see errno).
curses(3), menu(3).
The header file <menu.h> automatically includes the header
file <curses.h>.
These routines emulate the System V menu library. They were
not supported on Version 7 or BSD versions.
The user pointer should be a void pointer. We leave it as a
char pointer for SVr4 compatibility.
