|
|
\&\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 \fISSL_session_reused\fR\|(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.
|
|

|
|
\&\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).

The operation failed; check the error stack to find out the reason.
