Hi fellow Perlmonks! I am currently having fun with Net::SFTP::Foreign. I am modifying a deamon which monitors a directory and automatically uploads files via sftp to a server. If there are multiple files, the deamon forks a child process for every file and transfers them in parallel.
Now I want to do some better error handling. Wenn a transfer aborts, I want to print the number of bytes which were transferred. I can quite get this to STDOUT with the "more => -v" option.

my $sftp = Net::SFTP::Foreign->new(host =>$host, user => $user, key_pa
+th => [$privkey, $pubkey] , more => '-v');

[... debug output ...]
Transferred: sent 32700048, received 60544 bytes, in 1.6 seconds
Bytes per second: sent 20997978.1, received 38877.7
[... more debug output ..]

My first approach was, to grep that output for the "Transferred" line. While this does work, that seems a bit overkill.
I also tried utilizing the callback function of sftp->put like this:

my $BYTES = 0;

$sftp->put(               
    "testfile",           
    "testfile",           
    cleanup  => 1,        
    callback => sub {        
                          
        my ( $sftp, $data, $offset, $size ) = @_; 
        print $offset ." of ". $size ." bytes copied\n";
last_bytes($offset);                                                  
+          
    } );     

print "\nTransferred $BYTES bytes\n";
                                                                      
+                
sub last_bytes {
    my ($bytes) = @_;
    $BYTES = $bytes;
}

However this is giving me a hard time, as I would have to track a variable per child I fork.

In contrast, WWW::Curl has a method for getting the number of transferred bytes:

$curl->getinfo( CURLINFO_SIZE_UPLOAD );

I hope I am not missing something from the documentation for getting the transferred bytes from Net::SFTP::Forerign.... Any Ideas? I get the feeling I am nearly there with the callback-solution...

Kind regards,
