userptr(3menu)


NAME

   set_menu_userptr, 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

   ncurses(3NCURSES), menu(3MENU).

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.
