mitem_userptr(3X) mitem_userptr(3X)
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(3X), 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.
