|
|
\&\fISSL_SESSION_get_time()\fR returns the time at which the session \fBs\fR was
|
|
established. The time is given in seconds since the Epoch and therefore
|
|
compatible to the time delivered by the \fItime()\fR call.
|
|
.PP
|
|
\&\fISSL_SESSION_set_time()\fR replaces the creation time of the session \fBs\fR with
|
|
the chosen value \fBtm\fR.
|
|
.PP
|
|
\&\fISSL_SESSION_get_timeout()\fR returns the timeout value set for session \fBs\fR
|
|
in seconds.
|
|
.PP
|
|
\&\fISSL_SESSION_set_timeout()\fR sets the timeout value for session \fBs\fR in seconds
|
|
to \fBtm\fR.

|
|
The \fISSL_get_time()\fR, \fISSL_set_time()\fR, \fISSL_get_timeout()\fR, and \fISSL_set_timeout()\fR
|
|
functions are synonyms for the SSL_SESSION_*() counterparts.
|
|
.SH "NOTES"
|
|
.IX Header "NOTES"
|
|
Sessions are expired by examining the creation time and the timeout value.
|
|
Both are set at creation time of the session to the actual time and the
|
|
default timeout value at creation, respectively, as set by
|
|
\&\fISSL_CTX_set_timeout\fR\|(3).
|
|
Using these functions it is possible to extend or shorten the lifetime
|
|
of the session.
|
|
.SH "RETURN VALUES"
|
|
.IX Header "RETURN VALUES"
|

\&\fISSL_SESSION_get_time()\fR and \fISSL_SESSION_get_timeout()\fR return the currently
