When the session is set, the reference count of \fBsession\fR is incremented by 1. If the session is not reused, the reference count is decremented again during \fBSSL_connect()\fR. Whether the session was reused can be queried with the \fBSSL_session_reused\fR\|(3) call. .PP If there is already a session set inside \fBssl\fR (because it was set with \&\fBSSL_set_session()\fR before or because the same \fBssl\fR was already used for a connection), \fBSSL_SESSION_free()\fR will be called for that session. If that old session is still \fBopen\fR, it is considered bad and will be removed from the session cache (if used). A session is considered open, if \fBSSL_shutdown\fR\|(3) was not called for the connection (or at least \fBSSL_set_shutdown\fR\|(3) was used to set the \s-1SSL_SENT_SHUTDOWN\s0 state). .SH "NOTES" .IX Header "NOTES" \&\s-1SSL_SESSION\s0 objects keep internal link information about the session cache list, when being inserted into one \s-1SSL_CTX\s0 object's session cache. One \s-1SSL_SESSION\s0 object, regardless of its reference count, must therefore only be used with one \s-1SSL_CTX\s0 object (and the \s-1SSL\s0 objects created from this \s-1SSL_CTX\s0 object). .SH "RETURN VALUES" .IX Header "RETURN VALUES" The following return values can occur: .IP "0" 4 The operation failed; check the error stack to find out the reason. .IP "1" 4 .IX Item "1" The operation succeeded. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBssl\fR\|(7), \fBSSL_SESSION_free\fR\|(3), \&\fBSSL_get_session\fR\|(3), \&\fBSSL_session_reused\fR\|(3), \&\fBSSL_CTX_set_session_cache_mode\fR\|(3) .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2000\-2016 The OpenSSL Project Authors.
