+\&\fISSL_free()\fR decrements the reference count of \fBssl\fR, and removes the \s-1SSL\s0
+structure pointed to by \fBssl\fR and frees up the allocated memory if the
+the reference count has reached 0.
+.SH "NOTES"
+.IX Header "NOTES"
+\&\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
+failure.
+.PP
+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.
