OpenSSL configuration cleanup functions

Synopsis

 #include <openssl/conf.h>

 void CONF_modules_finish(void);
 void CONF_modules_unload(int all);

 void CONF_modules_free(void)
 #endif

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 finish handler to free up any configuration that module may have performed.

CONF_modules_unload() finishes and unloads configuration modules. If all is set to 0 only modules loaded from DSOs will be unloads. If all is 1 all modules, including builtin modules will be unloaded.

Return Values

None of the functions return a value.
