Hi everybody! I need to overwrite a file that other processes read from time to time, so I don't want it to end up being read when it's half written.

So I'm looking for a module that handles this, basically writes to a temp file, then unlinks the old file, and renames the tempfile to the old name.

Does this exist or do I have to write it? Thanks!

P.S. The double buffer reference is to graphics redraws, where you don't want to see a flash. 

my $copilot = [ "Perl" ]
bless $copilot;
