GNU SASL uses GnuTLS to do STARTTLS for IMAP and SMTP, look at
src/gsasl.c, although it is a rather complex example. GnuTLS doesn't
care if you use starttls, the API you use are the same, so you could
take a look at the examples in the manual:
http://www.gnu.org/software/gnutls/manual/html_node/Simple-client-example-with-anonymous-authentication.html
Insert your read/write's to negotiate STARTTLS in the unprotected
protocol, right after the call to tcp_connect().
