Example of a perl callback with send()

[Gary Mills]

The Cyrus::IMAP perl library describes send() this way:

       $client->send(\&callback, \&cbdata, $format, ...);

However, none of the examples I could find uses the callback and
callback data arguments.  Does anybody have an example of how
these are used.

I'm designing a perl script that makes several IMAP connections to
the server, to send long-running commands in parallel.  In this case,
the script can't block on a send().  It needs to issue all of them
and then poll for results.  I'm assuming that a perl callback along
with processoneevent() will make this possible.
