\&\fISSL_free()\fR also calls the \fIfree()\fRing procedures for indirectly affected items, if

applicable: the buffering \s-1BIO\s0, the read and write BIOs,

cipher lists specially created for this \fBssl\fR, the \fB\s-1SSL_SESSION\s0\fR.

Do not explicitly free these indirectly freed up items before or after

calling \fISSL_free()\fR, as trying to free things twice may lead to program

The ssl session has reference counts from two users: the \s-1SSL\s0 object, for
|
|
which the reference count is removed by \fISSL_free()\fR and the internal
|
|
session cache. If the session is considered bad, because
|
|
SSL_shutdown(3) was not called for the connection
|
|
and SSL_set_shutdown(3) was not used to set the
|
|
\&\s-1SSL_SENT_SHUTDOWN\s0 state, the session will also be removed
|
|
from the session cache as required by \s-1RFC2246\s0.
