| =head1 NAME |
| |
| CONF_modules_free, CONF_modules_finish, CONF_modules_unload - |
| OpenSSL configuration cleanup functions |
| |
| =head1 SYNOPSIS |
| |
| #include <openssl/conf.h> |
| |
| void CONF_modules_finish(void); |
| void CONF_modules_unload(int all); |
| |
| The following functions have been deprecated since OpenSSL 1.1.0, and can be |
| hidden entirely by defining B<OPENSSL_API_COMPAT> with a suitable version value, |
| see L<openssl_user_macros(7)>: |
| |
| void CONF_modules_free(void); |
| |
| =head1 DESCRIPTION |
| |
| CONF_modules_free() closes down and frees up all memory allocated by all |
| configuration modules. Normally, in versions of OpenSSL prior to 1.1.0, |
| applications called |
| CONF_modules_free() at exit to tidy up any configuration performed. |
| |
| CONF_modules_finish() calls each configuration modules B<finish> handler |
| to free up any configuration that module may have performed. |
| |
| CONF_modules_unload() finishes and unloads configuration modules. If |
| B<all> is set to B<0> only modules loaded from DSOs will be unloads. If |
| B<all> is B<1> all modules, including built-in modules will be unloaded. |
| |
| =head1 RETURN VALUES |
| |
| None of the functions return a value. |

| CONF_modules_free() was deprecated in OpenSSL 1.1.0; do not use it. |
