Well, I think thats what I mean..

I'm using Net::Telnet to communicate with some network devices and I wish to store the entire conversation between my script and the device in a database.

Net::Telnet permits this by either specifying a file to write the log to or by passing a filehandle to an already open file.

e.g: 

$telnet->input_log("/tmp/filename.tmp");

$fh=new FileHandle;
$fh->open(">/tmp/filename.tmp");
$telnet->input_log($fh);

In order to save the log using this method I have to write the log to disk, then read it back into a variable, then write it to the db.

My question is, is there anyway of creating a filehandle, which doesn't write to a file, but buffers the data written to it, which I can retrieve at the end of the operation..

e.g: 

my $log="";
my $fh=new VFileHandle;
$fh->open();
#do stuff
$log=$fh->close();
##write the $log var to the database.
I've tried using the FileHandle module but can't work out what file/device to open to make this work.

If I make the filehandle object without opening a file I get a 'writing to closed filehandle' error..

Any help appreciated !

Thanks,

James
