menu_userptr(3X)              Library calls              menu_userptr(3X)

NAME         top

       set_menu_userptr, menu_userptr - associate application data with a
       menu item

SYNOPSIS         top

       #include <menu.h>

       int set_menu_userptr(MENU *menu, void *userptr);
       void *menu_userptr(const MENU *menu);

DESCRIPTION         top

       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.

RETURN VALUE         top

       menu_userptr returns a pointer (which may be NULL).  It does not
       set errno.

       set_menu_userptr returns E_OK (success).

PORTABILITY         top

       These 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.
