| 21 | =head1 DESCRIPTION
|
|---|
| 22 |
|
|---|
| 23 | CONF_modules_free() closes down and frees up all memory allocated by all
|
|---|
| 24 | configuration modules. 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.
|
|---|
