NAMEset_menu_userptr, 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);

---

DESCRIPTIONEvery 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 VALUEmenu_userptr returns a pointer (which may be NULL). It does not set errno. set_menu_userptr returns E_OK (success).

---

SEE ALSOcurses(3X), menu(3X).

---

NOTESThe header file <menu.h> automatically includes the header file <curses.h>.

---

PORTABILITYThese 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.
