set_menu_userptr(3)

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

       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 sup-
       ported on Version 7 or BSD versions.

       The user pointer should be a void pointer.   We	leave  it  as  a  char
       pointer for SVr4 compatibility.
