menu_userptr(3X)								 menu_userptr(3X)

NAME
       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);

DESCRIPTION
       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
       Except  for  menu_userptr  (which returns NULL on error), each function returns one of the
       following:

       E_OK The routine succeeded.

       E_SYSTEM_ERROR
	    System error occurred (see errno).

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

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

PORTABILITY
       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 compat-
       ibility.
