- associate application data with a menu item
int set_item_userptr(ITEM *item, void *userptr);
void *item_userptr(const ITEM *item);
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 function item_userptr
returns a pointer (possibly NULL
It does not set errno.
The set_item_userptr always returns E_OK (success).
The header file <menu.h>
automatically includes the header file
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.
