NAME
menu_userptr - associate application data with a menu itemSYNOPSIS
#include <menu.h>int set_menu_userptr(MENU *menu, void *userptr);
void *menu_userptr(const 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
Except for menu_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.
