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.
