MirOS Manual: item_userptr(3), mitem_userptr(3), set_item_userptr(3)


mitem_userptr(3)    UNIX Programmer's Manual     mitem_userptr(3)

NAME

     mitem_userptr - associate application data with a menu item

SYNOPSIS

     #include <menu.h>
     int set_item_userptr(ITEM *item, void *userptr);
     void *item_userptr(const ITEM *item);

DESCRIPTION

     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 that field.

RETURN VALUE

     Except for item_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(3), menu(3).

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