An easy way to do this would be to use
IO::File's
new_tmpfile to create a temporary
file that will be automatically destroyed after it's closed, and possibly has no actual file on the file system. Then you can put the stuff to upload in that tempfile, rewind, and pass it to put():
use IO::File;
use Fcntl qw(:seek);
my $fh = IO::File->new_tmpfile
or die "Couldn't create tempfile: $!\n";
print $fh <<"END";
The contents of the file.
END
seek $fh, 0, SEEK_SET
or die "Couldn't rewind temp file: $!\n";
$ftp->put($fh, "ftptest");
close $fh;
# tempfile should be gone now.
update:
Note that $ftp->put(<SESAME>,"ftptest");
is not the right syntax to pass the SESAME file handle
to $ftp->put. It will pass every line of
the SESAME filehandle to it,
causing failures from an unfound local file with
a odd name.
The correct syntax would
probably be something like: $ftp->put(\*SESAME,"ftptest");
or $ftp->put(*SESAME,"ftptest");.
