CONF_MODULES_FREE(3)

NAME
CONF_modules_free, CONF_modules_finish, CONF_modules_unload - OpenSSL configuration cleanup functions

SYNOPSIS
#include <openssl/conf.h>
void
CONF_modules_free(void);
void
CONF_modules_finish(void);
void
CONF_modules_unload(int all);

DESCRIPTION
CONF_modules_free() closes down and frees up all memory allocated by all configuration modules.

CONF_modules_finish() calls the configuration finish handler of each configuration module 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 unloaded. If all is 1, all modules, including builtin modules, will be unloaded.

NOTES
Normally applications will only call CONF_modules_free() at application to tidy up any configuration performed.

RETURN VALUE
None of the functions return a value.
