Debconf::TmpFile - temporary file creator
=cut
package Debconf::TmpFile;
use warnings;
use strict;
use IO::File;
use Fcntl;

This module helps debconf make safe temporary files. At least, I think
they're safe, if /tmp is not on NFS.

Optionally a file extension may be passed to it.

my $ext=shift || '';
($fh, $filename) = File::Temp::tempfile(SUFFIX => $ext);
return $fh;
}
=item filename
Returns the name of the last opened temp file.
=cut
sub filename {
return $filename;
}
