int set_menu_userptr(MENU *menu, const void *userptr);
const 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 menudriver code leaves it alone). These functions get and set the menu user pointer field.
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.
