Normally, in versions of OpenSSL prior to 1.1.0, 25applications called 26CONF_modules_free() at exit to tidy up any configuration performed. 27 28CONF_modules_finish() calls each configuration modules B<finish> handler 29to free up any configuration that module may have performed. 30 31CONF_modules_unload() finishes and unloads configuration modules. If 32B<all> is set to B<0> only modules loaded from DSOs will be unloads. If 33B<all> is B<1> all modules, including built-in modules will be unloaded. 34 35=head1 RETURN VALUES 36 37None of the functions return a value. 38 39=head1 SEE ALSO 40 41L<config(5)>, L<OPENSSL_config(3)>, 42L<CONF_modules_load_file_ex(3)> 43 44=head1 HISTORY 45 46CONF_modules_free() was deprecated in OpenSSL 1.1.0; do not use it. 47For more information see L<OPENSSL_init_crypto(3)>. 48 49=head1 COPYRIGHT 50 51Copyright 2004-2021 The OpenSSL Project Authors.
