mitem_userptr(3)				 mitem_userptr(3)

NAME
       mitem_userptr  -	 associate  application	 data with a menu
       item

SYNOPSIS
       #include <menu.h>
       int set_item_userptr(ITEM *item, void *userptr);
       void *item_userptr(const ITEM *item);

DESCRIPTION
       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 that field.

RETURN VALUE
       Except  for  item_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(3), 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 compatibility.

AUTHORS
       Juergen	Pfeifer.   Manual  pages  and  adaptation for new
       curses by Eric S. Raymond.
