lpSecurityAttributes is ignored for Win9*.
Attribute FILE_FLAG_DELETE_ON_CLOSE -- is handy for creating temporary files. Indicates that the operating system is to delete the file immediately after all of its handles have been closed. So you don"t care to delete this file afterwards. When you do not need it anymore -- just close the handle or exit VFP.
The huge variety of avilable attributes makes this command very strong and sophisticated.
The function also can be used to put a message in a mailslot.
