mod_perl 1.29: send_fh(): result status?

[Brian Gorby]

I'm programming a web application that limits the number of downloads
for clients on certain files:

....
unless ( $r->header_only ) {
$r->send_fd($fh) ;
$self->record_downloa d($user_id, $file_id);
}
close($fh);

I'd like to be able to have some sort of confirmation that the file was
sent / received in entirety before recording the download; if the
download times out for whatever reason for the client, the download will
not be recorded.

Is this something that's possible in general? with mod_perl?
