set_item_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.
