           mitem_userptr  -  associate  application  data with a menu
           item

## SYNOPSIS

           #include
           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(3X), menu(3X).

## NOTES

           The header file  automatically includes the header
           file .

## 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.
