menu_userptr()

NAME

set_menu_userptr(), menu_userptr() - associate application data with a menu item

SYNOPSIS

#include <menu.h>

int set_menu_userptr(MENU *menu, char *userptr); char menu_userptr(MENU *menu);

DESCRIPTION

Every menu and 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 menu user pointer field.

RETURN VALUE

The function menu_userptr(3) returns NULL

The function set_menu_userptr(3) returns one of the following:

E_OK
The routine succeeded.
E_SYSTEM_ERROR
System error occurred (see errno

SEE ALSO

curses(3)

menus(3)

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.
