This implies, that all corresponding sessions from an 28external session cache are removed as well. If this is not desired, the user 29should explicitly unset the callback by calling 30SSL_CTX_sess_set_remove_cb(B<ctx>, NULL) prior to calling SSL_CTX_free(). 31 32=head1 RETURN VALUES 33 34SSL_CTX_free() does not provide diagnostic information. 35 36=head1 SEE ALSO 37 38L<SSL_CTX_new(3)|SSL_CTX_new(3)>, L<ssl(3)|ssl(3)>, 39L<SSL_CTX_sess_set_get_cb(3)|SSL_CTX_sess_set_get_cb(3)> 40 41=cut 42
