menu_userptr(3X)                                            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).

SEE ALSO         top

       curses(3X), menu(3X).

NOTES         top

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

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.
