Miscellaneous Library Functions                  menu_userptr(3X)



NAME
     menu_userptr - associate application data with a menu item

SYNOPSIS
     #include 
     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  automatically includes  the  header
     file .

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.
