Normally, in versions of OpenSSL prior to 1.1.0, 25 applications called 26 CONF_modules_free() at exit to tidy up any configuration performed. 27 28 CONF_modules_finish() calls each configuration modules B<finish> handler 29 to free up any configuration that module may have performed. 30 31 CONF_modules_unload() finishes and unloads configuration modules. If 32 B<all> is set to B<0> only modules loaded from DSOs will be unloads. If 33 B<all> is B<1> all modules, including builtin modules will be unloaded. 34 35 =head1 RETURN VALUES 36 37 None of the functions return a value. 38 39 =head1 SEE ALSO 40 41 L<config(5)>, L<OPENSSL_config(3)>, 42 L<CONF_modules_load_file(3)> 43 44 =head1 HISTORY 45 46 CONF_modules_free() was deprecated in OpenSSL 1.1.0; do not use it. 47 For more information see L<OPENSSL_init_crypto(3)>. 48 49 =head1 COPYRIGHT 50 51 Copyright 2004-2018 The OpenSSL Project Authors.
