Normally, in versions of OpenSSL prior to 1.1.0, 2513d40330Schristosapplications called 2613d40330SchristosCONF_modules_free() at exit to tidy up any configuration performed. 2713d40330Schristos 2813d40330SchristosCONF_modules_finish() calls each configuration modules B<finish> handler 2913d40330Schristosto free up any configuration that module may have performed. 3013d40330Schristos 3113d40330SchristosCONF_modules_unload() finishes and unloads configuration modules. If 3213d40330SchristosB<all> is set to B<0> only modules loaded from DSOs will be unloads. If 33*b0d17251SchristosB<all> is B<1> all modules, including built-in modules will be unloaded. 3413d40330Schristos 3513d40330Schristos=head1 RETURN VALUES 3613d40330Schristos 3713d40330SchristosNone of the functions return a value. 3813d40330Schristos 3913d40330Schristos=head1 SEE ALSO 4013d40330Schristos 4113d40330SchristosL<config(5)>, L<OPENSSL_config(3)>, 42*b0d17251SchristosL<CONF_modules_load_file_ex(3)> 4313d40330Schristos 4413d40330Schristos=head1 HISTORY 4513d40330Schristos 4613d40330SchristosCONF_modules_free() was deprecated in OpenSSL 1.1.0; do not use it. 4713d40330SchristosFor more information see L<OPENSSL_init_crypto(3)>. 4813d40330Schristos 4913d40330Schristos=head1 COPYRIGHT 5013d40330Schristos 51*b0d17251SchristosCopyright 2004-2021 The OpenSSL Project Authors.
