MirBSD manpage: menu_userptr(3), set_menu_userptr(3)

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.

          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.
