.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
Query, whether a reused session was negotiated during the handshake.
.SH "NOTES"
.IX Header "NOTES"
During the negotiation, a client can propose to reuse a session. The server
then looks up the session in its cache. If both client and server agree
on the session, it will be reused and a flag is being set that can be
queried by the application.
.SH "RETURN VALUES"
.IX Header "RETURN VALUES"
The following return values can occur:
.IP "0" 4
A new session was negotiated.
.IP "1" 4
.IX Item "1"
A session was reused.
