a7d27d5a
JR
205\fISSL_free()\fR also calls the \fIfree()\fRing procedures for indirectly affected items, if

207cipher lists specially created for this \fBssl\fR, the \fBSSL_SESSION\fR.
984263bc

208Do not explicitly free these indirectly freed up items before or after
209calling \fISSL_free()\fR, as trying to free things twice may lead to program
210failure.
211.PP
a7d27d5a 212The ssl session has reference counts from two users: the SSL object, for
984263bc
MD
213which the reference count is removed by \fISSL_free()\fR and the internal
214session cache. If the session is considered bad, because
215SSL_shutdown(3) was not called for the connection
216and SSL_set_shutdown(3) was not used to set the
a7d27d5a

217SSL_SENT_SHUTDOWN state, the session will also be removed
