menu_userptr - associate application data with a menu item |
#include <menu.h> |
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. |
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). |
curses(3X), menu(3X). |
The header file <menu.h> automatically includes the header file <curses.h>. |
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. |
