Hi all,

I wonder if someone could please clear something up for me. I want to
use the 'Delete(..)' primitive to remove a file on my local filesystem.
This requires that the file is open. I'm writing a delete procedure
that takes a string specifying the pathname of the file for deletion. I
have defined a package that provides functionality for opening a file
and holding information about it, including the File_Type instance
returned when the file is opened. Now, when *my* delete procedure is
called, I envoke the (my) function that attempts to open the file, in
order to obtain the File_Type instance required to call the Ada
library's Delete(..) primitive. Now comes the query. If the external-
file is already open, the exception 'Status_Error' gets thrown. That
*is* clear (LRM A.8.2[8]), but what isn't clear, is whether or not the
File_Type instance associated with the already-open external file is
supposed to be returned in the first (in/out) parameter of the Delete
primitive. If not, how can I obtain it, in order that I may actually
delete the file?

I hope the explanation is clear enough - if not pls ask me to clarify.
Thanks, Dom.
