# 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 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.

# SEE ALSO

conf, OPENSSL_config, CONF_modules_load_file

# HISTORY

CONF_modules_free(), CONF_modules_unload(), and `CONF_modules_finish()` first appeared in OpenSSL 0.9.7.
