menu_userptr(3x)                                       menu_userptr(3x)




NAME

       menu_userptr - associate application data with a menu item


SYNOPSIS

       #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

       menu_userptr returns a pointer (which may  be  NULL).   It
       does not set errno.

       set_menu_userptr returns E_OK (success).


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 is a void pointer.  We chose not to leave
       it as a char pointer for SVr4 compatibility.
