file_notice_changes RPC

[Wolfgang J�hrling]

Hi!

I tried to use the file_notice_changes() RPC. First, I created a port:

  err = mach_port_allocate (mach_task_self (),
                            MACH_PORT_RIGHT_RECEIVE,
                            &notify_port);

Then I opened a file on an ext2 file system:

  file = file_name_lookup ("foo", 0, 0);

But when I tried to request notification messages with

  err = file_notice_changes (file, notify_port, MACH_PORT_TYPE_SEND);

this failed with "(ipc/mig) server type check failure". What am I doing
wrong?

Thanks,
GNU/Wolfgang
