10 #include <openssl/conf.h>
11
12 void CONF_modules_finish(void);
13 void CONF_modules_unload(int all);
14
15Deprecated since OpenSSL 1.1.0, can be hidden entirely by defining
16B<OPENSSL_API_COMPAT> with a suitable version value, see
17L<openssl_user_macros(7)>:

19 void CONF_modules_free(void);
20
21=head1 DESCRIPTION
22
23CONF_modules_free() closes down and frees up all memory allocated by all
24configuration modules.  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.
