mitem_userptr - 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-spe‐
cific data (that is, the menu-driver code leaves it alone). These
functions get and set that field.
Except for item_userptr (which returns NULL on error), each function
returns one of the following:
E_OK The routine succeeded.
System error occurred (see errno).
SEE ALSOcurses(3X), menu(3X).
The header file <menu.h> automatically includes the header file
These routines emulate the System V menu library. They were not sup‐
ported on Version 7 or BSD versions.
The user pointer should be a void pointer. We leave it as a char
pointer for SVr4 compatibility.
