I would suggest that this is an operating-system issue.
Are you going to be using I/O packages supplied with your compiler (such as
Ada.Text_IO, Ada.Sequential_IO, and Ada.Direct_IO, for example), or are you
going to develop your own?
In the latter case, you will want to check to see what locking facilities
the operating system provides, and make use of them. In the former case,
you will want to check either the supplied documentation, or, failing that
the supplied source code (if it is supplied) to see: (a) whether the I/O
packages automatically do file locking; (b) whether they provide an option
for file locking; and (c) if so, whether it is adequate for your needs.
Nick.
