Описание (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.
Возвращаемое значение (Return value)
The function item_userptr
returns a pointer (possibly NULL
). It
does not set errno
.
The set_item_userptr
always returns E_OK
(success).

Портативность (Portability)
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.
