.IX Title "SSL_set_session 3"
.TH SSL_set_session 3 "0.9.7b" "2001-10-12" "OpenSSL"
.UC
.SH "NAME"
SSL_set_session \- set a \s-1TLS/SSL\s0 session to be used during \s-1TLS/SSL\s0 connect
.SH "LIBRARY"
libcrypto, -lcrypto
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
.Vb 1
\& #include <openssl/ssl.h>
.Ve
.Vb 1
\& int SSL_set_session(SSL *ssl, SSL_SESSION *session);
.Ve
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
\&\fISSL_set_session()\fR sets \fBsession\fR to be used when the \s-1TLS/SSL\s0 connection
is to be established. \fISSL_set_session()\fR is only useful for \s-1TLS/SSL\s0 clients.
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 \fISSL_connect()\fR. Whether the session was reused can be queried
with the SSL_session_reused(3) call.
.PP
If there is already a session set inside \fBssl\fR (because it was set with
\&\fISSL_set_session()\fR before or because the same \fBssl\fR was already used for
a connection), \fISSL_SESSION_free()\fR will be called for that session.
.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.
