CONF_modules_free(3)

NAME
 CONF_modules_free, CONF_modules_load, CONF_modules_unload -
 OpenSSL configuration cleanup functions

SYNOPSIS
 #include <openssl/conf.h>

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

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

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.

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.
